| 摘 要： | 为了进一步研究钢筋混凝土核心筒体的抗震性能和影响因素,在国内外试验研究的基础上对2个较大比例、大高宽比的钢筋混凝土核心筒试件进行了水平低周反复荷载试验,重点研究了不同轴压比下核心筒的破坏机理、承载能力、耗能能力、延性、剪力滞后等方面的抗震性能.研究发现,核心筒试件最后均为底部发生整体弯曲破坏,随着轴压比值从0.2增加到0.5,核心筒试件的刚度和承载能力有明显提高,但同时延性性能显著下降.分析表明:轴压比对钢筋混凝土核心筒的抗震性能有较大影响.

| Abstract: | In order to further study the seismic behavior of reinforced concrete core wall and factors influencing,two reinforced concrete core wall models with large height-width ratio were built and tested to failure under the combined action of constant axial load and reversed cyclic lateral load.The axial compression ratio on each core wall was different.This paper presents the results,including failure mode,hysteretic behavior,load-carrying capacity,ductility,energy dissipation ability,shear lag effect.The final ... |
