Extended evolutionary structural optimization method for multi-storey buildings

TL;DRAbstract

This study extends the Evolutionary Structural Optimization (ESO) method for application to multi-storey buildings. The objective is to find the optimal topologies of multi-storey buildings subject to overall stiffness or displacement constraints. It emphasizes the derivation of a methodology to help the structural designers to choose the optimal topology among many topologies that are generated during the evolutionary optimization process. Other problems of the ESO method such as the termination condition, sharp change in structural mean compliance or constrained displacements are also investigated. The new added features provide the ESO method with the capability of dealing with structures containing different types of finite elements. For the structure being considered, only continuum elements are allowed to be removed during the optimization process while beam elements are assumed to be fixed and are referred to as a non-design domain. By having all the topologies with the same wei
