(1 RBS Architecture Engineer Design Associate, Guangzhou 510170, China; 2 Guangzhou Scientific Computing Consultants Co., Ltd., Guangzhou 510170, China)Abstract: To evaluate rare-earthquake safety of a super high-rise shear-wall residential building structure in region of 8-degree of seismic precautionary intensity, the SAUSAGE software developed by Guangzhou Scientific Computing Consultants Co., Ltd. was applied in the structure's elasto-plastic time-history analysis under excitation of rare earthquakes. In view of solving problems with huge degrees of freedoms (DOFs) and time-consuming analysis caused by elasto-plastic fined finite element analysis( FEA) of super high-rise structures, theorem and advantages of SAUSAGE in
managing enormous DOFs and high nonlinearity were introduced. Under rare earthquakes in zone of high seismic precautionary intensity, super lugh-rise structures would be easily tumed to deep plastic. In solving tlus problem, efficient and effective elasto-plastic time-history analysis by SAUSAGE discovered the structure's vulnerable zone and revealed its failure characteristics, thus reflects some failure states of super high-rise structure under rare earthquake with FEA. The analysis here provides structural engineers helpful design guidance, and also preliminarily indicates SAUSAGE's powerful elasto-plastic analysis feature and widespread application prospect.
Keywords: super high-rise building; shear-wall structure; aseismic analysis; elasto-plastic time-history analysis
