Abstract

It is well known that the weight of the structural system for a high-rise building to resist lateral loads increases in nonlinear fashion with increase in building height and slenderness ratio. For a given building height or slenderness ratio, the weight of the structural system for a high-rise building subjected to lateral loads depends on the degree of stiffness of the building structure. Therefore, at the final stage of the structural design process, it has been a challenge to structural engineers to improve the efficiency of a structural system by either minimizing the weight of a structure for a given limit on lateral displacement or maximizing the degree of stiffness for a given weight of a structure. In this paper, a resizing design method that can minimize the magnitudes of lateral displacement and inter-story drift of a high-rise building with respect to structural weights is presented. Based on the proposed design method, the relation between the structural weight and the magnitude of lateral displacement is investigated using two examples, including a 60-story high-rise building.
