چکیده
Abstract Box girders bridges are widely used in modern highway systems because of their efficiency and attractive appearance. Vehicles loads represent one the mainly factors that influence structure reliability box bridges. Calculation bridge resistance with different stress due to vehicles as close possible real ones constitute premise a correct design structure. The goal this study is realize description regarding behavior analyzed under conditions. Nowadays finite element methods (FEM) highly capacity simulate evaluate By highlighting where maximum values appear we will help constructor avoid dangerous sections. Based on study, outline future research directions, aiming identify improve mechanical strength characteristics

Economical Steel Plate Girder Bridges
As a service to the bridge design profession, Bethlehem Steel has conducted hundreds of studies of steel plate girder bridges using its Preliminary Bridge Girder Optimization Program. The program is unique because it optimizes plate girder designs on the basis of least cost, not least weight. An evaluation of many study results leads to a number of guidelines which are offered in this paper. Wh...
متن کاملComposite Action during Construction of Steel Trapezoidal Box Girder Bridges (0-1898-2)
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 sect...
متن کاملLessons Learned in the Design and Erection of Box Girder Bridges from the West Gate
The West Gate Bridge, intended to span the Yarra River in Australia, collapsed during its third year of construction in 1970. Investigation into the project revealed numerous issues in the bridge's design and construction. The West Gate Bridge is one of a number of box girder bridges built during the mid 2 0 th century, and was one of four to fail in a three year period. An overview of the desi...
متن کاملPARAMETRIC STUDY: COST OPTIMIZATION OF NON-PRISMATIC REINFORCED CONCRETE BOX GIRDER BRIDGES WITH DIFFERENT NUMBER OF CELLS
In this paper the parametric study is carried out to investigate the effect of number of cells in optimal cost of the non-prismatic reinforced concrete (RC) box girder bridges. The variables are geometry of cross section, tapered length, concrete strength and reinforcement of the box girders and slabs that are obtained using ECBO metaheuristic algorithm. The design is based on AASHTO standard s...
متن کاملAccurate Stress Analysis on Steel Box Girder of Long Span Suspension Bridges Based on Multi-Scale Submodeling Method
The streamline flat steel box girder is broadly used in long span cablesupported bridges all over the world. As one of the most important part of the bridges, its stress level and distribution under various dynamic loads are especially concerned. However, it is difficult to obtain the accurate stress of the steel box girder by common finite element (FE) calculation. The Runyang Suspension Bridg...
