This book was released on 2005 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: In an effort to better understand the performance of bridges with fiber reinforced polymer (FRP) composite decks, four different deck systems were installed in a 207-meter, three-lane, five-span bridge in Dayton, Ohio. The spans range from 40 to 44 m, and the bridge consists of six steel girders. The span lengths and large number of panels created a unique opportunity to evaluate the response of four common FRP bridge deck systems under identical traffic and environmental conditions. Over a six-year period, the performance of the bridge and its components were monitored through field documentations, long-term continuous monitoring of key responses, controlled static and dynamic truck load tests conducted on a regular basis, and multi-reference modal tests performed in conjunction with the truck load tests. The measurements from nearly 300 sensors allowed a detailed evaluation of critical design issues such as the behavior of FRP panel-steel girder connections and connections between FRP panels, impact factor and distribution factors for bridges with FRP decks, thermal characteristics of FRP panels versus conventional reinforced concrete decks, critical role of thermal behavior of FRP panels on the overall performance, level of composite action, and serviceability issues for bridges with FRP decks. Based on the presented information, a number of recommendation for improved behavior are made.

This book was released on 2007 with total page 166 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wide-flanged concrete girders are increasingly being used for highway bridges in Wisconsin. The objective of this research was to understand the state of the art of non-metallic SIP forms and to develop design guidelines and performance specifications that can be used locally for the construction of highway bridge decks. Four major types of stay-in-place (SIP) forms using fiber reinforced concrete (FRC) or fiber reinforced polymer (FRP) materials were investigated: fiber reinforcements, grid reinforcements, bar reinforcements and pultruded profiles. The results were used to develop a model design and construction specification for non-structural, non-metallic, SIP forms in highway bridge decks.

Download or read book Structural Characteristics and Failure Prediction of Hybrid FRP-concrete Bridge Deck and Superstructure Systems written by and published by . This book was released on 2007 with total page 301 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is a major challenge to build bridge systems that have long-term durability and low maintenance requirements. A solution to this challenge may be to use new materials or to implement new structural systems. Fiber reinforced polymer (FRP) composites have continued to play an important role in solving some of persistent problems in infrastructure applications because of its high specific strength, light weight, and durability. Structural engineers always have valued the combination of materials into a hybrid structural system that takes advantage of the properties inherent in each of its constituents. In this study, the concept of the hybrid FRP-concrete structural systems is applied to both bridge superstructure and deck systems. The hybrid FRP-concrete bridge superstructure and deck systems are intended to have durable, structurally sound, and cost effective hybrid system that will take full advantage of the inherent properties of both FRP materials and concrete. The hybrid-FRP deck system can be installed in new construction, or can be attached to existing deck substructure after removing deteriorated concrete deck. In this study, two hybrid FRP-concrete bridge systems were investigated. The first system consists of trapezoidal cell units forming either a bridge superstructure or a bridge deck unit. The second one is formed by arch cells. The two systems rely on using cellular components to form the core of the deck system, and an outer shell to warp around those cells to form the integral unit of the bridge. Both systems were investigated analytically by using finite element (FE) analysis. From the rigorous FE studies, it was concluded that first system is more efficient than the second. Therefore, the first hybrid FRP-concrete system had been used to investigate the feasibility of the FRP-concrete structural systems in the remainder of the study. The proposed system consists of trapezoidal FRP cell units surrounded by an FRP outer shell forming a bridge system. A thin layer of concrete was placed in the compression zone. Concrete was confined by GFRP laminates which provide protection from environmental exposure. Moreover, the concrete layers reduce the local deformation of the top surface of the bridge under concentrated loads. Webs of the box section were designed at an incline to reduce shear force between sections. For the experimental phase of the study, a prototype bridge superstructure was designed as a simply-supported single span one-lane bridge with a span length of 18.3 m. Geometrical parameters of the proposed bridge system were determined by detailed finite element analyses. FEA was used to verify the structural behavior of this hybrid bridge superstructure prior to embarking on manufacturing and testing. Performance of this hybrid bridge superstructure was examined both experimentally and computationally. A test specimen, fabricated as a one-fourth scale model of the prototype bridge, was subjected to a series of loading tests: nondestructive tests (flexure, off-axis flexure, and negative flexure), and destructive tests (flexure and shear). Also, as a trial case for FRP-concrete bridge deck supported on steel girders, a prototype bridge system was designed as a simply supported steel bridge with a hybrid FRP-concrete deck. Details for connecting the hybrid decks with steel girders were investigated both experimentally and computationally. A test specimen, fabricated as a 3/4 scale model of the prototype bridge, was evaluated by series of service flexural loading tests under different loading conditions. Moreover, the composite action between the hybrid deck and steel girders was analyzed and tested. The effective flange width in the hybrid FRP-concrete deck acting compositely with the steel girders was evaluated at service conditions. Three different constitutive models for GFRP composites were integrated in the finite element analysis to examine the inelastic behavior and to predict failure of both the hybrid bridge deck and superstructure. Results from the both experimental and computational analysis for both the hybrid bridge superstructure and deck systems confirmed that the hybrid FRP-concrete bridge systems have an excellent performance from structural engineering point of view. The experimental results showed robust performance where cracking in the exterior GFRP laminates, interface failure, and slippage between GFRP and concrete under AASHTO design loads for the hybrid bridge superstructure were not exhibited. Also, both test specimens satisfied the AASHTO live load deflection limit. In addition, the shear connections at girder-deck interface of the deck specimen on steel girders demonstrated an excellent performance under service load. Furthermore, it was observed that the hybrid deck and the steel girders are interacting as a partially composite system under service-load conditions. The effective flange width for hybrid decks are less than AASHTO prescribed effective width for reinforced concrete decks. It was shown that a detailed finite element analysis could predict behavior of the test specimens under different loading conditions up to the failure point.

Book Synopsis Development of Composite Renewal Systems for Rapid Rehabilitation and Construction of Bridge Decks by : Anna Beth Pridmore
Download or read book Development of Composite Renewal Systems for Rapid Rehabilitation and Construction of Bridge Decks written by Anna Beth Pridmore and published by . This book was released on 2009 with total page 379 pages. Available in PDF, EPUB and Kindle. Book excerpt: The deterioration of steel in aging reinforced concrete bridges is a continual problem which could benefit from improved rehabilitation techniques that take advantage of enhanced and more durable materials such as fiber reinforced polymer (FRP) composites. Appropriately designed hybrid material systems benefit from the performance and durability advantages of FRP materials yet remain more cost effective than comparable all-composite systems. Development of rapid rehabilitation systems for the decks of concrete box girder bridges, which are increasingly common throughout the United States, is presented. One goal of this research is to assess and validate the use of FRP composite panels for use as both stay-in-place formwork and as the bottom longitudinal and transverse reinforcement in the deck of concrete box girder bridges. Performance assessments for full-scale two-cell box girder bridge specimens through monotonic and extensive cyclic loading provided validation for the FRP panel system bridge deck as a viable rehabilitation solution for box girder bridge decks. The FRP panel system performed comparably to a conventionally reinforced concrete bridge deck in terms of serviceability, deflection profiles, and system level structural interaction and performed superior to the RC bridge deck in terms of residual deflections, and structural response under cyclic loading. Assessment of a damaged FRP panel bridge deck system, which was repaired using a resin injection technique, showed superior performance for the repaired system in terms of integrity of the FRP panel interface and cyclic response. Rapid rehabilitation techniques for strengthening reinforced concrete box girder bridge deck overhangs using near-surface-mounted (NSM) carbon fiber reinforced polymer (CFRP) were also evaluated. Analytical predictions of load carrying capacity and deflections provided correlation with experimental results, and the developed analysis methods provide an effective design tool for future research. Results from the laboratory testing of a bridge deck overhang strengthened with FRP showed significant increases in load carrying capacity as well as deformation capacity as compared to the as-built specimen without FRP. This research provides enhanced understanding of hybrid structures and indicates significant potential for rehabilitation applications to concrete box girder bridges.

Book Synopsis Evaluation of Post-tension Strengthened Steel Girder Bridge Using FRP Bars by : Terry J. Wipf
Download or read book Evaluation of Post-tension Strengthened Steel Girder Bridge Using FRP Bars written by Terry J. Wipf and published by . This book was released on 2003 with total page 88 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many state, county, and local agencies are faced with deteriorating bridge infrastructure composed of a large percentage of relatively short to medium span bridges. In many cases, these older structures are rolled or welded longitudinal steel stringers acting compositely with a reinforced concrete deck. Most of these bridges, although still in service, need some level of strengthening due to increases in legal live loads or loss of capacity due to deterioration. Although these bridges are overstressed in most instances, they do not warrant replacement; thus, structurally efficient but cost-effective means of strengthening needs to be employed. In the past, the use of bolted steel cover plates or angles was a common retrofit option for strengthening such bridges. However, the time and labor involved to attach such a strengthening system can sometimes be prohibitive. This project was funded through the Federal Highway Administration's Innovative Bridge Research and Construction program. The goal is to retrofit an existing structurally deficient, three-span continuous steel stringer bridge using an innovative technique that involves the application of post-tensioning forces; the post-tensioning forces were applied using fiber reinforced polymer post-tensioning bars. When compared to other strengthening methods, the use of carbon fiber reinforced polymer composite materials is very appealing in that they are highly resistant to corrosion, have a low weight, and have a high tensile strength. Before the post-tensioning system was installed, a diagnostic load test was conducted on the subject bridge to establish a baseline behavior of the unstrengthened bridge. During the process of installing the post-tensioning hardware and stressing the system, both the bridge and the post-tensioning system were monitored. The installation of the hardware was followed by a follow-up diagnostic load test to assess the effectiveness of the post-tensioning strengthening system. Additional load tests were performed over a period of two years to identify any changes in the strengthening system with time. Laboratory testing of several typical carbon fiber reinforced polymer bar specimens was also conducted to more thoroughly understand their behavior. This report documents the design, installation, and field testing of the strengthening system and bridge.
