Title The Design of Huanya Skyscraper in Nanjing - Internal Force Calculation and Earthquake Response Analysis of Superstructure
Abstract In the paper, according to the engineering background of Huanya Skyscraper in Nanjing, the author uses PKPM family software to complete the structural design, calculation and optimization。 The SATWE software was used to complete internal force calculation and time-historic analysis under frequent earthquake of superstructure。 The EPDA was used to complete the nonlinear time-historic analysis under rarely occurred earthquake of superstructure。 The most reasonable plan was selected after internal force calculation among the structural arrangements and dimensions initially set。 The time-historic analysis completed by SATWE in this program, the results meet the regulatory requirements。 The results came from nonlinear time-historic analysis also satisfy the regulatory requirements, speed curve and hazardous displacement angle curve showed that the 5,6 layers are weak layers。 Also the short beam around the shear walls and the main beam from east to west in the first to second floor of annex are weak components。 The subsequent analysis gave the optimization design plan to original arrangement and dimensions to improve the seismic performance of buildings。
