This book was released on 2013-04-26 with total page 114 pages. Available in PDF, EPUB and Kindle. Book excerpt: On September 28, 1998, Hurricane Georges made landfall in the Ocean Springs/Biloxi, Mississippi area. On October 2, 1998, the Federal Emergency Management Agency (FEMA) Mitigation Directorate deployed a Building Performance Assessment Team (BPAT) to the Gulf Coast to assess damages caused by Hurricane Georges. The team included FEMA Headquarters and Regional Office engineers, planners, and a coastal geologist; consulting engineers; floodplain management specialists; and a forensic engineer. The BPAT.s mission was to assess the performance of buildings in the Gulf Coast area and make recommendations for improving building performance in future hurricanes. The assessment included areas of the Gulf Coast from Pensacola Beach, Florida, to Gulfport, Mississippi (including Mobile Bay, Alabama). In addition, a supplemental assessment of manufactured home performance was conducted in the Florida Keys. The assessment also included inland areas along major streams and rivers that experienced flooding. The BPAT process is intended to provide guidance to state and local governments on post-hurricane reconstruction and new construction with the goal of enhancing future building design and construction. This report presents the Federal Emergency Management Agency's (FEMA) Building Performance Assessment Team's (BPAT) observations on the success and failure of buildings in the Florida Keys and Gulf Coast areas of the United States to withstand the wind and flood forces generated by Hurricane Georges. Recommendations to improve the building performance in future natural disasters in this area are included as well.

Download or read book Development of a Regional Wind Risk Assessment Framework for Wood-frame Single-family Residential Building Stock written by Shuochuan Meng and published by . This book was released on 2023 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over the past few decades, residential buildings along the coastal areas of the United States have suffered enormous structural damage and economic losses due to hurricane strikes. The significant variations in the building characteristics of residential buildings lead to distinctive building-level vulnerabilities under extreme winds. Therefore, an accurate representation of the building inventory is critical for quantifying regional hurricane risk. In this dissertation, a regional wind risk assessment framework is developed to evaluate hurricane-induced structural damage and economic losses for residential communities. Unlike existing loss models that represent the building stock by archetype models with limited variations in building characteristics, the proposed framework applies site-specific risk assessments on every house in the region of interest based on parcel-based building inventories. A sensitivity analysis is conducted to investigate the effects of different building features on building vulnerability to identify the most critical features and explore the means of simplifying the building modeling process. To apply site-specific damage assessments at regional level, an automatic building modeling workflow is integrated into the framework, which is supported by property-specific characteristics extracted through machine learning-aided data collection approaches. The framework is applied to residential communities in New Hanover County, North Carolina. Through site-specific risk assessments on 1,746 realistic building models, the overall variance in building-level damage and loss results among single-family houses is evaluated. The damage results reveal significant differences in wind vulnerability due to variations in architectural features. Furthermore, a comparative study shows that the aggregated regional loss calculated based on refined building models is substantially higher than that derived from building archetypes used in existing regional loss models. The building inventory generation and building modeling modules integrated into the framework largely reduce the inherent uncertainties of hurricane risk prediction. The high-resolution damage and loss results produced by the framework offer insights into local risk conditions, which facilitate the improvement of hazard risk mitigation and post-disaster management strategies.

Download or read book CFD-Based Probabilistic Framework for Evaluation of Coastal Residential Buildings Under Combined Hurricane Wind and Surge Flood written by Mehrshad Amini and published by . This book was released on 2021 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Coastal residential buildings are vulnerable to significant damage due to hurricane related hazards such as storm surge, wind loads, and inundation. Recent damage to residential buildings caused by hurricanes in coastal areas illustrates poor performance of coastal structures against hurricane related hazards, which indicates that recent standards and building code provisions need to be improved in terms of loading and design requirements. A fundamental problem with current standards is that most follow the deterministic approach to some extent. For instance, both uncertainties regarding flood hazards and building structure characteristics such as elevation, number of stories, and size have not been considered in current flood risk assessment methods, which causes many concerns in terms of validity and reliability. On the other hand, Performance-Based Engineering (PBE) methodology is a well-known design approach to address inherent uncertainties for assessing and mitigating the risk associated with engineering structures. However, with only limited PBE frameworks in hurricane engineering fields proposed during recent years, there is lack of sufficient understanding of different aspects for development of standards needed for hurricane resistant design and retrofit of residential buildings. Furthermore, given the concurrent multi-hazard nature of hurricanes, designers need to address more complex loading conditions and design decisions. Based on the performance of coastal residential buildings in past hurricanes, elevating the lowest floor above the expected Base Flood Elevation (BFE) has been found to be the most effective strategy to reduce direct damage caused by flood and storm surge. However, elevated buildings can be exposed to different levels of wind loads due to unique aerodynamic characteristics, which leads to the need for more stringent design of structural and foundation systems. In addition, past hurricanes have shown that the actual flood levels can be several feet higher than the BFE, which means even pile-elevated houses may still be vulnerable to damage. Therefore, some communities encourage homeowners to add freeboard to the specific BFE in order to mitigate the risk of damage. The amount of freeboard depends on many factors, for which there is no rational approach for building owners and designers to make the most efficient decision. This study proposes a probabilistic framework in order to investigate the combined interaction of hurricane wind and coastal surge flood on typical residential homes upgraded based on various retrofit strategies. The goal of developing such a framework is to contribute to holistic and quantitative approach in evaluating the potential damage to retrofitted, particularly elevated coastal residential buildings. This proposed probabilistic framework consists of four main modules, namely hazard analysis, structural analysis, damage assessment, and loss measurement. A literature review was carried out to evaluate the performance of coastal residential buildings with respect to direct and indirect damage. The result of the literature review on mitigation techniques are discussed according to hurricane wind and flood-related hazards. Identification and quantification of these hurricane-associated hazards is the first step to understanding the behavior of residential buildings and identifying common failure mechanisms and mitigation techniques. The Computational Fluid Dynamic (CFD) analysis was performed to obtain realistic loading scenarios (wind and wave effects) and corresponding engineering demand parameters, respectively. A comprehensive parametric analysis was conducted to understand the effect of various factors, including wind angle, wave type (regular and irregular waves), building elevation, and pier distribution on wind- and wave-induced loads on elevated coastal residential buildings. The CFD models were validated based on available data in terms of wind and wave loadings separately due to lack of current laboratory experiments. The resistance capacities and statistical characteristics for various building components under positive and negative pressures were obtained from experimental tests available in the literature review. The procedure relies on the Monte Carlo Simulation (MCS) to propagate uncertainties through the CFD analysis. Finally, damage assessment and vulnerability analysis were conducted based on selected failure criteria (e.g., HAZUS database) to develop physics-based fragility curves based on four different damage states, and finally obtain loss curves in terms of the building elevation for the selected residential building. A typical wood-frame residential building was selected for the case study to develop the fragility curves for four damage states and the corresponding loss curve based on HAZUS-MH. The building was assumed to be located in the Bolivar Peninsula, where it was heavily impacted by Hurricane Ike as a Category 2 storm. The fragility curves and loss curve were developed for two different scenarios: the building with 8d and 6d common nails used for the connection of roof and floor sheathings. These loss curves predict the expected damage ratio of the building due to combined effects of wind and waves considering the specific house elevation, which can help design professionals and home builders in order to select a reasonable freeboard above the base flood elevation determined based on a probabilistic approach rather than available deterministic methods. This framework can also be utilized in risk assessment and decision analysis of other types of structures against various environmental hazards.

Download or read book A Damage Assessment and Wind Loading Analysis of Residential Structures Built Post-1996 in Punta Gorda in the Wake of Hurricane Charley written by James Newberry and published by . This book was released on 2006 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: ABSTRACT: One of the communities in the path of Hurricane Charley as it came ashore August 13, 2004, was Punta Gorda, recording gusts up to 145 mph. This project utilizes aerial photos taken approximately 10 days after the storm battered the area, using a digital photography program. Focusing on the one-story residential structures (houses) of the Punta Gorda area, a damage assessment could be made of the area's homes, and how they stood up to the storm. This study focused further on homes built after major changes to the local/state building codes went into effect (starting in 1996) after the devastation left in south Florida by Hurricane Andrew in 1992. After selecting approximately 20 damaged houses, damaged from wind loading only, an analysis of these houses (or types of houses) could then be undertaken complying with the most current building/wind codes used at the time of Charley's landfall. Furthermore, by looking at the pictures, and using reports outlining the types of damage seen from the storm, the building/wind codes could then be checked for their effectiveness. After performing a wind loading analysis on houses similar to those seen in the selected pictures, and using the wind code provisions of ASCE 7-98, calculations show a substantial increase in local wind pressure to various zones of the roof. High pressure zones of the roof included the ridges of the gable and hipped style roofs, as well as the corners and the edges. More emphasis needs to be placed on the installation of the clay tiles (mandated by certain deed-restricted subdivisions of Punta Gorda). If the tiles are ripped off from the wind, then the roof sheathing becomes exposed to the environment, and if this becomes damaged, rain leaking down into the interior of the house would cause additional damage.

Download or read book Mitigation Assessment Team Report: Hurricane Charley in Florida - Observations, Recommendations, and Technical Guidance (FEMA 488) written by U. s. Department of Homeland Security and published by Createspace Independent Pub. This book was released on 2013-04-26 with total page 320 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hurricane Charley made landfall on Friday, August 13, 2004, at Mangrove Point, just southwest of Punta Gorda, Florida. On August 19, 2004, the Federal Emergency Management Agency's (FEMA's) Mitigation Division deployed a Mitigation Assessment Team (MAT) to Florida to assess damages caused by Hurricane Charley. This report presents the MAT's observations, conclusions, and recommendations in response to those field investigations. Several maps included in our first chapter illustrate the path of the storm, the wind field estimates, the impact on people and infrastructure, and the depth of storm surge along the path. The width of the high-wind field was very narrow even though hurricane force winds affected some portion of the Florida peninsula from Punta Gorda to Daytona Beach. There was little storm surge or coastal flooding because of the narrow size of the storm and the translational speed with which it came ashore and crossed the state. The hurricane is believed to have been a design wind event (the wind speeds equaled or exceeded those delineated in the current version of the Florida Building Code [FBC]) for a narrow area from the point of landfall on the west coast inland for 120 miles. The design wind speed for Charlotte County (Punta Gorda) per the FBC is 114 to 130 mph (measured as a 3-second peak gust). The actual measured wind speed near Punta Gorda was 112 mph (3-second peak gust) and measured speeds in other parts of the state suggest that Charley was a design wind event. The storm created a very small area affected by storm surge and most damage was not caused by flooding from storm surge, waves, or erosion. Because Hurricane Charley was a design level wind event, the resultant storm damage provides valuable evidence about the effectiveness of building codes and design practices as they ad¬dress design guidelines for high winds. For buildings built prior to the adoption of the current codes, judgments were made about how the observed damage was reflective of the code to which the building was constructed, and the quality of construction or the inspection process that followed construction. Consideration also was given to the type and use of buildings. Many buildings that were expected to function for critical/essential services were severely damaged by the hurricane and lost function for significant periods of time after the event. The recommendations in this report are based solely on the observations and conclusions of the MAT, and are intended to assist the State of Florida, local communities, businesses, and individ¬uals in the reconstruction process and to help reduce damage and impact from future natural events similar to Hurricane Charley. The general recommendations presented in Section 8.1 relate to policies and education/outreach that are needed to ensure that designers, contractors, and building officials understand the requirements for disaster resistance construction in hurricane-prone regions.

Download or read book Physically-based Visualization of Residential Building Damage Process in Hurricane written by Dezhi Liao and published by . This book was released on 2007 with total page 131 pages. Available in PDF, EPUB and Kindle. Book excerpt: This research provides realistic techniques to visualize the process of damage to residential building caused by hurricane force winds. Three methods are implemented to make the visualization useful for educating the public about mitigation measures for their homes. First, the underline physics uses Quick Collision Response Calculation. This is an iterative method, which can tune the accuracy and the performance to calculate collision response between building components. Secondly, the damage process is designed as a Time-scalable Process. By attaching a damage time tag for each building component, the visualization process is treated as a geometry animation allowing users to navigate in the visualization. The detached building components move in response to the wind force that is calculated using qualitative rather than quantitative techniques. The results are acceptable for instructional systems but not for engineering analysis. Quick Damage Prediction is achieved by using a database query instead of using a Monte-Carlo simulation. The database is based on HAZUSRTM engineering analysis data which gives it validity. A reasoning mechanism based on the definition of the overall building damage in HAZUSRTM is used to determine the damage state of selected building components including roof cover, roof sheathing, wall, openings and roof-wall connections. Exposure settings of environmental aspects of the simulated environment, such as ocean, trees, cloud and rain are integrated into a scene-graph based graphics engine. Based on the graphics engine and the physics engine, a procedural modeling method is used to efficiently render residential buildings. The resulting program, Hurricane!, is an instructional program for public education useful in schools and museum exhibits.

Download or read book Summary Report on Building Performance - 2004 Hurricane Season (FEMA 490) written by Federal Emergency Agency and published by FEMA. This book was released on 2013-04-26 with total page 68 pages. Available in PDF, EPUB and Kindle. Book excerpt: The nation will remember 2004 as a record-setting year in terms of presidential disaster declarations and administered disaster aid. In 2004, President Bush issued 68 disaster declarations of which 27 were due to hurricanes. Time and again the U.S. was impacted by hurricane force winds and waves that damaged cities and small towns in 15 states, Puerto Rico, and the U.S. Virgin Islands. Of all the regions that endured the hurricane season, the State of Florida bore the brunt of the record-setting storms as Hurricanes Charley, Frances, Ivan, and Jeanne tested the federal and state fortitude in disaster response and recovery. Communities were devastated as wind and water damage from the four storms battered residential, commercial, industrial, and public facilities. Disaster assistance totaling more than $4.4 billion was approved for Floridians, and to date, 1.24 million storm victims have applied for federal and state assistance (FEMA 2005b). The financial impact of the season will likely exceed $20 billion, according to preliminary loss estimates from the Insurance Services Office's Property Claim Services (PCS). The four hurricanes that struck Florida in 2004 were all significant events; however, the hurricanes were each distinctive in terms of their wind and water action and resulting damages. The first of these, Charley (designated a Category 4), was the first design level wind event to strike the U.S. mainland since Hurricane Andrew (1992) and caused more wind damage than flood damage. Frances (Category 2) and Jeanne (Category 3), while not as strong as Charley, were still very damaging hurricanes resulting in additional wind damage. Hurricane Ivan delivered not only strong winds (Category 3), but also caused significant flood damage to buildings and other structures, even those built above the 100-year flood elevation. The impact of the four hurricanes was intensified by their back-to-back occurrence; three of the hurricanes followed similar paths or had overlapping damage swaths. Frances and Jeanne followed almost identical paths across Florida from the east coast (around Port St. Lucie) to the west coast (north of Tampa area). These two very wide storms crossed the path of Charley (which traveled west to east) in central Florida creating an overlap of impacted areas in Orange, Osceola, Polk, and Hardee counties. As a result of these overlapping impact swaths, damage resulting from the later hurricanes (Frances and Jeanne) was difficult to distinguish from earlier damage caused by Charley. For instance, roofs that failed during Frances or Jeanne may have been weakened or damaged by Charley and more prone to failure. For this reason, most of the recommendations and conclusions contained in this report are based on observations made after Hurricanes Charley and Ivan and are supported by observations made after Hurricanes Frances and Jeanne. Following Hurricanes Charley and Ivan, the FEMA Mitigation Assessment Teams (MATs) performed field observations to determine how well buildings in Florida and Alabama performed under stresses caused by the storms' wind and water impacts. A Rapid Response Data Collection Team performed field observations after Hurricane Frances that focused on critical and essential facilities; however an assessment was not performed after Jeanne, because Jeanne and Frances impacted a similar region. Overall, the MAT observed building performance success in structural systems designed and built after Hurricane Andrew. This Summary Report focuses on the ongoing need for improvement in building performance.
