Optimization of Shape and Layout of High-rise Buildings which Evaluated Wind Force by RANS

Abstract

In recent years, optimization techniques for improving performance and streamlining designs are utilized in various fields. In the field of wind engineering, it is trying to utilize it when designing a structure advantageous to wind force. However, in the optimization calculation requiring more than 1000 cases to obtain the optimal solution, besides utilizing the RANS with a small calculation load, there is no option at present. Therefore, in this study, RANS was combined with the optimization calculation on the shape and layout of the building to reduce the wind force, and compared with the past experimental research. As a result, we combined RANS with optimization technology to grasp the building shape that is relatively advantageous against wind force.
