Shear wall layout optimization of multi-tower buildings based on conceptual design and extended evolutionary structural optimization method

Abstract

ABSTRACT In multi-tower buildings, the towers interact with each other because the bodies of each tower are connected by a podium, thus making the optimization design of this type of building challenging. Optimizing such structures will enable safer designs and the use of less material. To optimize the layout of shear walls in multi-tower building systems, an extended evolutionary structural optimization method based on a conceptual design method is proposed herein. The optimization process considers a complete range of professionally codified and construction constraints of building designs, making the method practical. Finally, some practical examples are presented to demonstrate that the proposed method can significantly improve the efficiency of the shear wall layout optimization for multi-tower buildings and obtain a result that satisfies the requirements of the specification.
