Available in PDF, EPUB and Kindle. Book excerpt: In steel trapezoidal box girder bridge systems, the U-shaped steel girder is designed to act compositely with the concrete deck to form a closed box for live loading. During the construction stage, however, the behavior is not well understood. The usual practice of assuming the system to be non-composite during construction requires substantial top flange bracing to form a quasi-closed box section. Composite box girders with live loading, and girders during construction, have to be evaluated during the design of curved steel trapezoidal box girder bridges. Considering both cases, the design for construction loading is the least understood and is the most important. Stresses due to construction loading can reach up to 60-70 percent of the total design stress for a given cross section. A three-phase study was undertaken to investigate the behavior of curved trapezoidal box girders during construction.

Book Synopsis LRFD Design of Double Composite Box Girder Bridges by : Purvik Patel
Download or read book LRFD Design of Double Composite Box Girder Bridges written by Purvik Patel and published by . This book was released on 2009 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: ABSTRACT: Conventional continuous steel bridges only exhibit composite behavior in the positive moment region. Similar composite action may also be achieved in the negative moment region by casting a bottom concrete slab between the points of inflection. Such a section is referred to as "double composite" since it is composite in both the positive and negative moment regions. Savings in double composite bridges arise because expensive steel is replaced by inexpensive concrete to carry compressive loads. Although double composite bridges have been designed and constructed since at least 1978 there has been limited research. Thus, current designs rely on existing provisions for designing conventional 'single' composite bridges. This fails to fully exploit the advantages or recognize the weaknesses, if any, of double composite action. This thesis presents findings from a cooperative research project involving USF/URS/FDOT in which full-scale tests and theoretical analyses were carried to develop appropriate limit state rules for designing double composite bridges. A 4 ft. deep, 48 ft. long, 16 ft. wide box girder bridge representing the entire negative moment section at a support of a continuous full-size box girder bridge was fabricated and tested at FDOT's Structural Research Center, Tallahassee under fatigue, service and ultimate loading. Based on the findings from these tests and non-linear finite element analyses conducted by USF, URS proposed new design rules. This thesis focuses on the applications of these rules to develop a model design example for use by bridge engineers. The example was specifically selected from AISI so that a cost comparison with conventional design could be made. For completeness, an overview of the experimental results is also included in the thesis.

This book was released on 2004 with total page 538 pages. Available in PDF, EPUB and Kindle. Book excerpt: Horizontally curved girder bridges have been used considerably in recent years in highly congested urban areas. However, although significant research on physical testing and advanced analysis has been underway for the past decade, the practical employment of many recommendations has not been achieved by the engineering community nor have standards reflecting this work been brought into practice. The design process of curved composite bridges involves tracking the stresses and the potential failure change in the girders during erection, construction and service loading stages. For structural safety and serviceability, the designer estimates the stresses induced within the bridge and assure that they do not exceed the applicable specified limit state as required in bridge design standards. However, the designer may be concerned about the level of approximation that is used in his estimate or even the applicability of the underlying theory. To answer this question and provide the designer with more insight into the behavior of the curved bridges, the field testing during construction and service loading of a curved bridge located near Baltimore, Maryland is re-examined here using linear elastic three-dimensional finite element modeling. Comparisons are made between the finite element results and the measured results. Finally, to facilitate the finite element modeling effort for use by a designer, ANSYS Parametric Design Language (APDL) capabilities are used here to develop an analysis/design tool for "Bath-Tub" style curved steel girder bridges. This tool is then used to evaluate the effects of several important design variables on the response and behavior of the girders during the construction phase. This study demonstrates the ability of finite element modeling to assess the stiffness, serviceability performance, buckling behavior and ultimate strength of curved bridges during construction and it is a major step towards a performance based approach to design for stability. The level of safety or reliability that would be available during the erection and the construction processes of horizontally curved girder bridges represents another major concern for the designer. A three span continuous curved box girder bridge in Houston, Texas is used in this study as an example reflecting current detailing and fabricating practice and it is chosen for a detailed evaluation of the structural safety/reliability during the erection and construction process. This task involves simulating the girder erection and concrete slab placement sequence of the bridge using comprehensive nonlinear three dimensional finite element modeling.
