A Proposed Transfinite Super-tall International Square Structure Design and Analysis

The main body height of an international square structure is 200. 200 m,which is a concrete framecore tube structure system; It is a hight of class B structure,which has al weak layer. It is also vertical irregular. SATWE was used to calculate elastic basic mechanics performance of the main structure,and compare the calculation results with the results of PMSAP module. The seismic behavior of the structure was explored. Under severe earthquake,the pushover analysis and dynamic elastic-plastic time history analysis were implemented though PKPM EPDAPUSH. Elastic analysis indicates that the engineering calculation results are good,and the overall results meet the specification requirements. Elastic-plastic time history analysis shows that the structure has good seismic performance and can meet the predetermined seismic performance goals. Besides,some technology measures were adopted to strengthen the weak parts.
