Title

A Novel Approach To Analyze Existing Bridges Efficiently

Abstract

Analyses of existing bridges are conducted for different reasons such as load rating and retrofit simulations. It is desirable to have full 3D finite element models for analysis purposes; however, development of such models may not be feasible since these 3D models require considerable time, effort and expertise. As a result, AASHTO provides practical methods for the analysis of the bridges. The basic approach which is commonly used by design offices, DOT engineers and other practitioners is the beam line analysis using distribution factors. The recent AASHTO LRFD Bridge Design Specifications provides formulations where span length, beam spacing, beam stiffness and slab thickness are used to obtain girder moment and shear distribution factors. © 2009 ASCE.
