Abstract:Based on the complex outofcode connected structure of Zhengdong Business Center, programs of SATWE, YJKS and MIDAS Building were used to analyze and calculate the structure under the frequent, fortification and rare earthquakes respectively. Static elastoplastic analysis in elasticplastic stage was conducted to obtain the overall performance and dynamic characteristics. According to the structural characteristics, reasonable seismic performance objectives of the structure were selected. Through the calculation of the structure under the fortification and rare earthquakes, the performance of the structure fulfilled the requirements of the seismic performance objectives.
Keywords:complex connected structure; outofcode highrise structure; performancebased seismic design; static elastoplastic analysis
