［摘要］為研究鋼管混凝土疊合邊框內(nèi)藏鋼桁架剪力墻的抗震性能，制作了2個(gè)普通鋼管混凝土疊合邊框剪力墻試件和2個(gè)鋼管混凝土疊合邊框內(nèi)藏鋼桁架剪力墻試件。對(duì)試件進(jìn)行了模擬地震振動(dòng)臺(tái)試驗(yàn)研究，對(duì)比了這2種剪力墻的動(dòng)力特性、加速度時(shí)程反應(yīng)和位移時(shí)程反應(yīng)。利用有限元軟件ABAQUS分別建立微觀(guān)模型和宏觀(guān)模型對(duì)不同設(shè)計(jì)參數(shù)的試件進(jìn)行了彈塑性時(shí)程分析。研究結(jié)果表明，內(nèi)藏鋼桁架能夠明顯提高鋼管混凝土疊合邊框剪力墻的延性和抗震耗能能力；在較大的地面加速度峰值下，鋼桁架減小試件地震位移的作用發(fā)揮得更明顯；鋼管混凝土疊合邊框內(nèi)部鋼管壁厚的增大有利于提高剪力墻的承載力和安全儲(chǔ)備。

Abstract:In order to study the seismic behavior of shear wall with steel tube-reinforced concrete columns and concealed steel trusses, two ordinary shear wall specimens with steel tube-reinforced concrete columns were made as well as two shear wall specimens with steel tube-reinforced concrete columns and concealed steel trusses. First, the specimens were tested on the shaking table. The dynamic characteristic, acceleration time-history response and displacement time-history response of specimens were contrastively analyzed. In addition, microscopic and macroscopic models were made using finite element analysis software of ABAQUS to conduct the elastic-plastic time-history analysis of specimens with different design parameters. The study proves that the concealed steel trusses can significantly improve ductility and energy dissipation capacity of shear wall specimens with steel tube-reinforced concrete columns; the function of steel trusses to reduce displacement response is more obvious when the value of peak acceleration on the ground is larger; it is profitable for improving bearing capacity and safety margin of the shear wall to increase the wall thickness of internal steel tubes.

Keywords:steel tube-reinforced concrete columns; concealed steel truss; shear wall; shaking table test; elastic-plastic time-history analysis
