This book was released on 2016 with total page 100 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the present research, load distribution factors of steel-concrete composite bridges subjected to loads recommended by Australian Bridge Design Code are determined. The bridges can have straight or curved (in plan) alignments with box girder or I girder sectional configurations. The load distribution factors are quite useful in bridge design practice specifically at their preliminary design stage. These factors help a designer to quickly calculate the stress resultants (shear force or bending moment) acting on different girders of a bridge from those acting on the entire bridge section which can be estimated easily in the case of a statically determinant structure such as simply supported straight bridge treated as a beam. Unfortunately, the horizontally curved bridges are statically indeterminate even if they are idealized as a curved beam. In order to address this issue, a closed form analytical solution without having any major simplification is developed which can be conveniently used by a designer for calculating the stress resultants acting on the entire section of a curved bridge. The unit load method, a method extracted from Castigliano's second theorem, is used to derive the analytical solution. As bridge loads consist of a number of wheel loads, the use of influence line diagrams is quite common as they help to calculate the maximum values of any parameter such as bending moment conveniently. For this purpose, the analytical solution is used to obtain the influence line diagram of shear force, bending moment and torsion of curved bridges. A detailed finite element modelling of these bridge structures is used to calculate the load distribution factors. In order to have a reliable finite element model of these structural system, different types of element such as solid element, shell element and beam element are used in different combinations to find out the most suitable option that can accurately simulate the components of these bridge systems with reasonable computational efficiency. The performance of these finite element models is assessed using experimental results available in literature. These bridges can be characterized with different parameters and these parameters can vary in a wide range in real scenario. Thus there is a need for development of design formulae or charts for load distribution factors in terms of these parameters that can be readily used for designing any bridge. For this purpose, a large number of configurations of these bridges are generated by varying their different parameters and these bridges are analysed using the abovementioned finite element model. A large number of results obtained from these analyses are used to develop the design guidelines in the form of empirical expressions using multivariate regression analysis.

Book Synopsis Composite Action During Construction of Steel Trapezoidal Box Girder Bridges by :
Download or read book Composite Action During Construction of Steel Trapezoidal Box Girder Bridges written by and published by . This book was released on 2005 with total page 58 pages. 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 Single Lane Live Load Distribution Factor for Decked Precast/prestressed Concrete Girder Bridges by : John Zhongguo
Download or read book Single Lane Live Load Distribution Factor for Decked Precast/prestressed Concrete Girder Bridges written by John Zhongguo and published by . This book was released on 2005 with total page 448 pages. Available in PDF, EPUB and Kindle. Book excerpt: The live load distribution factor (DF) equations provided by AASHTO-LRFD for the decked precast/prestressed concrete (DPPC) girder bridge system do not differentiate between a single or multilane loaded condition. This practice results in a single lane load rating penalty for DPPC girder bridges. The objective of this project is to determine DF equations which accurately predict the distribution factor of the DPPC girder bridge system when it is only subjected to single lane loading. Eight DPPC girder bridges were instrumented. Each bridge was loaded with a single load vehicle to simulate the single lane loaded condition. The experimental data was used to calibrate 3D FE models and 2D grillage models of the DPPC girder bridge system. The calibrated models were used to conduct a parametric study of the DPPC girder bridge system subjected to a single lane loaded condition. Two sets of new equations that describe the single lane loaded distribution factor for both shear and moment forces of these bridges are proposed and compared with AASHTOLRFD DF equations.
