Abstract:The out-of-code high-rise structure of a commercial apartment features plane irregularity, concave-convex irregularity, transferring layer and partial vertical component discontinuity. SATWE and MIDAS/Building software were used to carry out the elastic time-history analysis under wind loads and earthquakes, and the performance objectives of each part of the structure under the action of frequent earthquakes were verified. The dynamic elastic-plastic time-history analysis of the structure was carried out by using ABAQUS software, and plastic damage conditions of transferring layer floors were analyzed. The calculation results show that the selected structural system is reasonable, safe and reliable, and all the performances of the structure can reach the predetermined seismic performance targets.

Keywords:out-of-code high-rise structure; seismic performance; dynamic elastic-plastic time-history analysis
