Abstract

The goal of bridge engineers has always been to design economical structures that are safe, serviceable and durable. In order to assess the performance and safety of these bridges, one of the analytical methods employed is finite-element (FE) modeling. This method involves breaking down the bridge structure into an assembly of finite-sized elements. The behavior of the elements and the overall structure can be obtained by formulating a series of constitutive relationships and algebraic equations that can be readily solved with computer processors.;Extensive research is being carried out to develop efficient finite element programs for bridge design. As a part of continuing research at West Virginia University to conduct parametric studies on in-service and model bridges, this work aims to develop a convenient and reliable analysis platform.;This is accomplished by creating a Graphical User Interface (GUI) for modeling 3D bridges that uses ABAQUS as the analysis tool. With the use of influence surfaces generated by the post-processor also developed in this research, variable loading conditions can be simulated to calculate the maximum force effects in the bridge superstructure.
