摘要
采用SAUSAGE软件对深圳某宿舍楼进行动力弹塑性时程分析,选取三条地震波(CCTW1982、IV172、RH2TG40)输入模型,评估结构性能。结果表明:大震作用下该结构弹塑性模型位移时程达到峰值点周期明显边长,结构进入塑性状态,基底剪力相比弹性模型变小,结构产生耗能;其变形指标满足规范要求,大部分连梁出现中度至严重损坏,发挥出耗能作用,剪力墙、转换柱、转换梁发生轻微及轻度损坏,满足大震性能目标。
SAUSAGE software was used to analyze the dynamic elastoplastic time history of a dormitory building in Shenzhen,and three seismic waves(CCTW1982,IV172,and RH2TG40)were selected to input into the model to evaluate the structural performance.The results show that the displacement time history of the elastoplastic model of the structure reaches the peak point under the action of large earthquakes,and the period is significantly longer.The structure enters a plastic state,and the base shear force of the substrate becomes smaller than that of the elastic model,resulting in energy dissipation of the structure.Its deformation index meets the requirements of the specification,and most of the connecting beams are moderately to severely damaged,which plays an energy-dissipating role,and the shear wall,conversion column,and conversion beam are slightly and slightly damaged,meeting the performance target of large earthquakes.
