摘要
为了研究斜柱角度对新型斜柱转换结构抗震性能的影响,利用Abaqus建立5榀新型斜柱转换结构实体模型,斜柱角度分别为55°、60°、65°、70°、75°,对其施加低周水平往复荷载进行分析。对其滞回曲线、骨架曲线、承载能力、位移延性、刚度退化综合比较,结果表明:当斜柱角度为60°~70°时,新型斜柱转换结构的耗能能力、延性、刚度等综合性能较好,具有较强的抗震性能。
To study how angle of inclined column affects the seismic behavior of a new inclined column transfer structure,5 finite element models(by Abaqus) of the structure under low cyclic reversed loading are studied when angle of the inclined columns is 55°,60°,65°,70° and 75°,respectively. A comprehensive comparison of these models on hysteretic curves,skeleton curves,bearing capacity,displacement ductility and stiffness degradation shows that,when the angle of inclined column is between 60° and 70°,the new inclined column transfer structure shows a much better comprehensive capacity on energy dissipation capacity,ductility,rigidity,etc. and thus can achieve a better seismic behavior.
