APPLICATION OF TOPOLOGY OPTIMIZATION IN DESIGN OF R.C. STRUCTURES USING STRUT-AND-TIE METHOD

Abstract

Abstract

The concept of structural optimization has recently gained a lot of attention. Topology optimization in particular has been under continuous development due to its applicability to wide range of engineering problems spanning even beyond structural applications. Great deal of concern was being given to the algorithms of topology optimization utilizing the state of the art technology as well as heightened computing speeds found nowadays. Topology optimization has been the focus of attention for the engineering society for many years. However, very few research can be found regarding the application of the topology optimization procedures in the design of reinforced concrete structures especially when linked with strut-and-tie method which is a method proved to be quite adequate in the design of reinforced concrete structure with great accuracy. This study was conducted in order to further strengthen the link between topology optimization and the strut-and-tie method which is a widely implemented design method by most of the design codes, and utilize those two powerful tools in the design of complex reinforced concrete structures. Moreover, a program capable of performing topology optimization algorithm to simple as well as complex structures and design the critical elements of the structure was developed. The code for the program was developed using MATLAB software to constitute the adopted topology optimization algorithm, along with SAP2000 which is a widely spread and well developed structural analysis program used to perform analyses.
