The seismic nonlinear static analysis comparison of high-rise building using different frame system configuration

Abstract

The dimensions and arrangement of columns have a significant impact on the seismic behavior of a structure. The objective of this paper is to ascertain the appropriate dimensions and configuration of columns for a building utilizing a frame system and framed tube system. Various column sizes and configurations were utilized to model four different types of buildings. The pushover analysis method was employed to determine the deformation capacity. The results obtained from the pushover analysis, indicate that the drift ratio for each building model remains below the prescribed 2% drift limit. The fourth building model, known as the framed tube system, exhibits the lowest drift ratio among the models, measuring at 0.81%. Upon reviewing the budget plan, it is evident that the second model building exhibits the lowest cost, displaying a notable disparity of 20.98% in comparison to the fourth model building, which boasts the highest cost. After considering both structural performance and budgeted cost, it is determined that the framed tube structural system is the optimal configuration.
