开孔三重钢管防屈曲耗能支撑性能试验研究
|
摘要
设计制作两种开孔三重钢管防屈曲耗能支撑和一种不开孔三重钢管防屈曲耗能支撑试件,并对其进行低周反复加载试验,研究开孔三重钢管防屈曲耗能支撑的性能、核心钢管开孔与否防屈曲耗能支撑性能的差异、开孔排数对支撑性能的影响以及支撑的恢复力模型和破坏特征,并采用ABAQUS有限元软件对其进行分析。研究结果表明:开孔三重钢管防屈曲耗能支撑的滞回性能稳定,耗能能力强;核心钢管开孔后降低了支撑的屈服点且增大了支撑的延性;开孔三重钢管防屈曲耗能支撑的恢复力模型可采用对称的双线性模型来描述;试验结果与有限元分析结果基本吻合。
Two perforating triple-steel tube buckling-restrained brace(PBRB) and one non-perforating triple-steel tube buckling-restrained brace(BRB) were designed and constructed.Reversed cyclic loading tests were carried out to study the hysteretic performance of PBRB and BRB,the influences on performance of PBRB with different perforation numbers,the restoring force model and the failure characteristics of BRB and PBRB.ABAQUS was used to study the performance of BRB and PBRB.The results indicate that PBRB show stable hysteretic performance and higher energy dissipation capacity.The yield point of PBRB is reduced while the ductility increased.The restoring force models of BRB and PBRB can both adopt the bilinear model.The ABAQUS analysis results are basically consistent with the testing results.
