| 摘 要： | 为了考察轴压比对蜂窝状钢骨混凝土L形柱抗震性能的影响,本文进行了3根不同轴压比的蜂窝状钢骨混凝土L形柱的低周往复水平荷载试验,研究了该L形柱的破坏形态、滞回特性、延性、黏滞阻尼系数等抗震性能.研究表明:蜂窝状钢骨能增强钢骨与混凝土间的黏结能力,提高其协同工作与整体受力性能.蜂窝状钢骨的存在,延缓了L形柱的刚度退化,提高了延性,增强了结构的耗能能力及抗震性能.轴压比对该新型构件的破坏形态及抗震性能影响明显.随着轴压比的增大,构件的破坏形态由类似于剪切破坏向轴压破坏形态转变.轴压比越大,构件的极限承载力越大,但延性与黏滞阻尼系数越小,耗能能力越低,抗震性能越差.研究还发现,该新型构件的正、反方向承载力及延性有所差别.

| Abstract: | In order to inspect the seismic behavior of honeycomb steel-reinforced concrete L-shaped columns with different axial compression ratios,the low cyclic reversed lateral loading tests were carried out for three honeycomb steel-reinforced concrete L-shaped columns with different axial compression ratios,and the seismic behavior such as failure mechanism,hysteretic characteristic,ductility and viscous damping of the L-shaped column was studied.The test results show that honeycomb steel can increase the adhesiv... |
