This book was released on 2015 with total page 107 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis presents a seismic evaluation of the unreinforced masonry buildings in Boston Massachusetts's historical Back Bay neighborhood. This Boston district, famous for its rows of Victorian brownstone residences is considered to be one of the best preserved examples of 19 'h century urban design. There are a few specific reasons to speculate at the vulnerability of this neighborhood to seismic events. First, in 1755, one hundred years before the Back Bay started to be built, the most massive earthquake of New England's history occurred, damaging unreinforced masonry structures in Boston. Approximately eighty percent of the Back Bay neighborhood is now made up of unreinforced masonry structures. Second, seismic design was not required in Boston until 1975, which means a staggering majority of the buildings in the Back Bay were constructed without any kind of anti-seismic lateral system. The aim of this thesis is to assess the structural response of the unreinforced masonry homes of the Back Bay to seismic activity due to these issues. A case study of an unreinforced masonry building in the neighborhood is assessed through structural analysis of its facade and party walls. The performance of this building is extrapolated to represent the state of the unreinforced masonry buildings of the Back Bay.

Download or read book Design of Reinforced Concrete Buildings for Seismic Performance written by Mark Aschheim and published by CRC Press. This book was released on 2019-04-05 with total page 576 pages. Available in PDF, EPUB and Kindle. Book excerpt: The costs of inadequate earthquake engineering are huge, especially for reinforced concrete buildings. This book presents the principles of earthquake-resistant structural engineering, and uses the latest tools and techniques to give practical design guidance to address single or multiple seismic performance levels. It presents an elegant, simple and theoretically coherent design framework. Required strength is determined on the basis of an estimated yield displacement and desired limits of system ductility and drift demands. A simple deterministic approach is presented along with its elaboration into a probabilistic treatment that allows for design to limit annual probabilities of failure. The design method allows the seismic force resisting system to be designed on the basis of elastic analysis results, while nonlinear analysis is used for performance verification. Detailing requirements of ACI 318 and Eurocode 8 are presented. Students will benefit from the coverage of seismology, structural dynamics, reinforced concrete, and capacity design approaches, which allows the book to be used as a foundation text in earthquake engineering.

Download or read book Seismic Analysis of Multi-Story Unreinforced Masonry Buildings with Flexible Diaphragms written by Juan Aleman Hernandez and published by . This book was released on 2014 with total page 374 pages. Available in PDF, EPUB and Kindle. Book excerpt: Studies regarding the regional seismicity of New York City (NYC) indicate that earthquakes of magnitude greater than or equal to 5 have a 20-40% probability of occurring in a 50 year period. Considering that more than 50% of the large population of the region (19.1 million) is living in an area where 80% of the buildings are of old Unreinforced Masonry (URM) construction, it is likely that even a moderate earthquake could have critical consequences on public safety and the economy of this area. The main goal of this study was to develop simulation capabilities supported by experimental testing to evaluate the seismic performance of typical unreinforced masonry buildings with flexible diaphragms located in NYC. Simplified nonlinear macro-models of wood diaphragms, masonry walls and floor-to-wall connections were developed and validated individually using data from past experiments. The models are implemented in both commercial and research software to demonstrate their practical use. In particular, a new approach for modeling flexible diaphragms is proposed that is shown to provide similar accuracy to detailed finite element models at a fraction of the computation cost. The models developed were also validated as at the system level, through shake table testing of two full-scale specimens conducted as part of this study. The specimens were designed and constructed to represent the expected loading conditions of a central portion of a one-story URM building and constructed of materials representative of older masonry construction. The tests provide a unique data set that captures the interaction between flexible floors, out-of-plane walls and their connections at, full scale.The validated macro-models can be used for performance-based seismic assessment of unreinforced masonry building in NYC and elsewhere. To demonstrate their use, preliminary studies were conducted to develop out-of-plane URM fragility curves, a building-specific collapse fragility function, and estimate the seismic response of the building when subjected to a ground shaking intensity similar to the 2011 Virginia Earthquake. The probabilistic framework and new performance definitions provided by the FEMA P58 project were used to conduct a performance-based seismic assessment for an archetype unreinforced masonry building in New York City with an emphasis on out-of-plane behavior. This preliminary study served to demonstrate the applicability of the proposed models for applications in performance-based design.

This book was released on 2021 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The seismic evaluation of existing unreinforced masonry (URM) structures is deemed essential due to their historical value and the vulnerability they present when subjected to earthquake shaking. Most of these buildings, constructed in the last century, do not comply with the current seismic codes and masonry standard. This study focusses on the assessment of URM walls subjected to lateral loading and more in detail to the behaviour of structural components such as the piers and spandrels. The behavior of structural elements, comprising the shear and bending failure modes, are investigated; these failure modes can be detected through the crack propagation initiated in building's masonry walls. Then, a parametric study on a series of capacity formulations of piers and spandrels is performed and each failure mode is investigated independently in the aim of assessing the accuracy in capturing their strength. Three experimental test data are used to validate the efficiency of formulations for diagonal shear and data from five testing programs are used to validate the proposed formulations used to predict the maximum shear force resulting from flexural behavior of piers. Subsequently, a deterministic model for piers is built using an open-source software to generate data required to build a linear relationship between different parameters and the performance criteria expressed in terms of strength and ductility. A case study comprising an URM facade wall of an existing 2-storey school building in Montreal is also conducted and certain strengthening interventions are presented. Further, the generated data is used to build probabilistic models that operates on Bayesian Networks. Nonlinear analysis using the target and the predictive variables are carried out. Machine learning algorithms are applied to acquire the entropy reduction factors which helps determining the most predictive variables used to assess the performance of piers.

Available in PDF, EPUB and Kindle. Book excerpt: In the past, facilities considered to be at the end of their useful life were demolished and replaced with new ones that better met the functional requirements of modern society, including new safety standards. Humankind has recently recognised the threats to the environment and to our limited natural resources due to our relentless determination to destroy the old and build anew. With the awareness of these constraints and the emphasis on sustainability, in future the majority of old structures will be retrofitted to extend their service life as long as feasible. In keeping with this new approach, the EU’s Construction Products Regulation 305/2011, which is the basis of the Eurocodes, included the sustainable use of resources as an "Essential Requirement" for construction. So, the forthcoming second generation of EN-Eurocodes will cover not only the design of new structures, but the rehabilitation of existing ones as well. Most of the existing building stock and civil infrastructures are seismically deficient. When the time comes for a decision to prolong their service life with the help of structural and architectural upgrading, seismic retrofitting may be needed. Further, it is often decided to enhance the earthquake resistance of facilities that still meet their functional requirements and fulfil their purpose, if they are not earthquake-safe. In order to decide how badly a structure needs seismic upgrading or to prioritise it in a population of structures, a seismic evaluation is needed, which also serves as a guide for the extent and type of strengthening. Seismic codes do not sufficiently cover the delicate phase of seismic evaluation nor the many potential technical options for seismic upgrading; therefore research is on-going and the state-of-the-art is constantly evolving. All the more so as seismic evaluation and rehabilitation demand considerable expertise, to make best use of the available safety margins in the existing structure, to adapt the engineering capabilities and techniques at hand to the particularities of a project, to minimise disruption of use, etc. Further, as old structures are very diverse in terms of their materials and layout, seismic retrofitting does not lend itself to straightforward codified procedures or cook-book approaches. As such, seismic evaluation and rehabilitation need the best that the current state-of-the-art can offer on all aspects of earthquake engineering. This volume serves this need, as it gathers the most recent research of top seismic experts from around the world on seismic evaluation, retrofitting and closely related subjects.

This book was released on 2012 with total page 352 pages. Available in PDF, EPUB and Kindle. Book excerpt: The research in this thesis was conducted with the primary aims of seismically assessing the current stock of Pakistan unreinforced masonry (URM) buildings and investigating seismic retrofit of New Zealand URM buildings using fibre reinforced polymer (FRP) materials. Seismic assessment of Pakistan URM buildings was conducted by adopting three international rapid evaluation methods for Pakistan conditions. Assessment case studies of major cities of Pakistan were performed and it was concluded that the New Zealand method is applicable with certain modifications to Pakistan URM buildings. The focus of the second part of this research was on seismic retrofit of in-plane loaded walls, that are likely to fail in a shear mode, as such failures are commonly observed in earthquakes. FRP materials have become popular in recent years, but limited test data, and design guidelines exist for their use on URM walls. The experimental part of this included seventeen monotonic diagonal compression tests, six reverse cyclic diagonal compression tests, and six horizontal shear tests on unretrofitted and FRP-retrofitted walls. The research showed that FRP is highly effective in increasing shear strength, pseudo-ductility and toughness, which are important parameters in seismic design. Horizontal shear tests on flanged walls, with realistic boundary conditions, confirmed the effectiveness of FRP for enhancement of shear strength of URM. Simple finite element (FE) models were presented in this research using a commercial FE software. The models were effective in simulating the behaviour and shear stress of wallettes retrofitted with full surface fabrics and strips that were oriented along the wallette diagonals. A guide for the design of in-plane loaded walls that are retrofitted with externally bonded FRP materials was presented. Design expressions were developed from the basic principle and were correlated to the experimental results. Design examples were also included.
