Prediction of Torsional Behavior for High-Rise Building Structures under Lateral Load
횡하중에 의한 고층건물의 비틀림 거동분석
Abstract
It is recommended to have symmetric plan and elevation in structural design of hight-rise building structures to reduce torsional response of the structures. However it is not always allowed to do so due to architectural purposes. in many cases high-rise buildings are asymmetric. The purpose of this study is to predict the torsional behavior of high-rise building structures with asymmetric plan. Equivalent lateral stiffness and deformation shape factor are used for prediction of torsional response of high-rise buildings. Overall torsion of a structure is estimated by equivalent lateral stiffness and torsion of each floor is estimated by deformation factor in each 2-D lateral force resisting elements.
