STRUCTURAL TOPOLOGY OPTIMIZATION OF STEEL SECTION USING SIMP TECHNIQUE

Abstract

In the twentieth century, architect and designers have utilized inventive and new techniques to create effective and optimum types of structures. These innovative designers employed the techniques that give rise to effective, aesthetic and novel shape but they all have common restriction. Every technique used by these designers needed that within structures number of openings needed to be known prior to the structure obtained by these techniques. These techniques required the use of same type of model. But in Topology optimisation, this restriction does not restrict the formation of new structures which only required the design domain to be defined by the designer. Topology Optimisation also gives the advantage of optimising the openings in the structure and provides an innovative novel section in the study of novel structural shapes. In 1988, Topology optimisation was introduced. It is a mathematical method to optimise the structures. Elements are selected in a FE mesh which represents the given design domain and then effectively optimises the material to the minimum as well as maximise the strength for the given process. The result obtained from topology optimisation show the similarity to the structures which are found in nature. Structures found in nature are generally structurally efficient and aesthetically pleasing
