| 摘 要： | 为研究黏滞阻尼器腋撑对钢筋混凝土框架结构抗震性能的影响，设计制作了带黏滞阻尼器腋撑的钢筋混凝土框架模型和普通框架模型各1榀，对其进行水平正弦稳态激励荷载作用下的抗震性能试验，研究了两榀框架的滞回特性、耗能能力以及关键测点应变等。试验结果表明：设置黏滞阻尼器腋撑框架的滞回曲线较普通框架饱满，结构的耗能能力及附加阻尼比显著提高；激振频率变化对两榀框架的滞回特性以及钢筋应变影响较小；设置黏滞阻尼器腋撑可较大幅度降低梁柱节点处的内力，延缓框架柱顶塑性铰的产生和发展，有效地保护梁柱节点，改善钢筋混凝土框架的抗震性能，但黏滞阻尼器腋撑加大了梁柱加腋处及柱脚的内力；带黏滞阻尼器腋撑钢筋混凝土框架和普通框架均为柱脚塑性铰发展严重而破坏。

| Abstract: | In order to investigate the seismic performance of the reinforced concrete(RC) frame with viscous damper haunch braces(VDHB),a RC frame model with VDHB and a general RC frame model were designed and their seismic performances were studied experimentally subjected to sine waveform steady-state excitations.Seismic behavior such as hysteretic performance,energy dissipation capacity and reinforcement strain at key measuring points of these specimens were investigated.The investigation results indicate that comp... |
