Abstract

The problems of lateral displacement control and usability of a structure are treated as the main part in high-rise buildings. Lateral displacement and usability control can be effectively managed through stiffness design. In this paper the non-dominated sorted genetic algorithm, NSGA-II, which may be used to satisfy many objective functions is applied to the structural design of high-rise buildings. However, the rate of convergence is slower because the number of structural analysis and the amount of calculation increases. The resizing technique is efficient for displacement control because of the redistribution within the structure. An important objective is to improve the convergence speed by using the optimal design technique because the algorithm finds an optimal solution without sensitivity analysis and complex calculations.
