Simplified Computation of Elastic-Plastic Displacement Response of High-Rise Steel Structure under Earthquake Considering Torsional Effect
Considering unavoidability of torsional vibration of high-rise buildings during earthquake, for a simpler and more accurate way to compute the maximum interstory drifts, through establishment of different structure calculation model. Structure analysis program CANNY 3D was used to conduct 3D and 2D time-history analyses on irregular steel structure models under frequently occurred small earthquakes and large earthquakes. Finally, by comparing maximum interstory drifts between each floor, a method was presented to simplify 3D computation of elastic-plastic interstory displacement of high-rise irregular steel structure into a computation plane 2D structure.
