SHAPE DESIGN OF BRIDGE COLLAPSE PROTECTION BRACKET APPLYING TOPOLOGY OPTIMIZATION TECHNIQUES

Abstract

A lightweight and exceptionally rigid cast metal configuration has been carrying out technological development through the implementation of a topology optimization technique for a bracket designed for a bridge collapse prevention system. Nonetheless, the configuration derived from rudimentary unitary analysis did not result in optimal performance when subjected to combined analysis replicating the installation state. Consequently, for the purpose of enhancing performance, formulated an optimization method encompassing meticulously devised analytical conditions. The configuration obtained through this method is approximately 30% lighter than the conventional shape, while maintains equivalent or heightened rigidity.
