Computational Analysis and Design of Bridge Structures

Bridges consist of super- and substructures. Superstructures, often called bridge deck structures, are traditionally analyzed by the deck itself for load-distribution behavior. With the invention of computers and the creation of bridge-related software, the approximation can be minimized and tedious processes can be streamlined. It is now possible to change the structural parameters, even structural types, during the design process, because the computer program can now recalculate stresses, deflections, and internal forces in seconds. Through the advances in computer graphic capabilities, meshing in the preprocess and contour displaying on the fly in the post process are the norms of almost all bridge analysis and design computer programs. With today’s power of both hardware and software, more sophisticated three-dimensional (3D) finite element models have been used in the design of many major structures, in part or all. Based on current availability and future potential, high-performance computer hardware and advanced software technologies can even provide an unprecedented opportunity to develop a new generation of integrated analysis and design systems with roads and bridges to benefit not only new bridge design but also routine load rating and maintenance of existing bridges
