［摘要］對鋼管混凝土邊框鋼板剪力墻試件和鋼管混凝土邊框內藏鋼板剪力墻試件進行了模擬地震振動臺試驗，試件高寬比均為3.2。在試驗的基礎上，利用ABAQUS軟件和SAP2000軟件分別建立實體模型和宏觀模型，對試件進行了彈塑性時程分析，對比了計算結果和實測結果，研究了不同鋼板寬厚比和鋼管壁厚對試件抗震性能的影響。研究結果表明：鋼管混凝土邊框內藏鋼板剪力墻試件的延性較好，抗震耗能能力較強，可在高層建筑中設計使用；而在兩種試件當中，鋼管混凝土邊框和鋼板（內藏鋼板）起到的耗能作用均比較突出。［關鍵詞］鋼管混凝土邊框; 鋼板; 剪力墻; 振動臺試驗; 彈塑性時程分析中圖分類號：TU375 文獻標識碼：A 文章編號：1002-848X(2016)06-0049-06
Elastic-plastic time history analysis on high shear wall with concrete-filled steel tubular frame and embedded steel plateWang Yaohong1, Cao Wanlin2, Yang Yabin3(1 Civil Engineering Institute, Inner Mongolia University of Technology, Hohhot 010051, China; 2 College of Architecture and Civil Engineering, Beijing University of Technology, Beijing 100124, China; 3 School of Civil Engineering and Communication, North China University of Water Resources and Electric Power, Zhengzhou 450045, China)Abstract: Two steel plate shear walls were tested on the shaking table. One was steel plate shear wall with concrete-filled steel tubular(CFST) frame and another was composite shear wall with concrete-filled steel tubular frame and embedded steel plate. The height to width ratio of two specimens was 3.2. Based on the experimental study, solid model and macroscopic model were established using ABAQUS and SAP2000 programs respectively. The elastic-plastic time history analyses were conducted on the two specimens to compare calculated results and field measured results and to study effects of different steel plate's height to width ratios and thickness of steel tubes on seismic performances of the specimens. The study results show that: the ductility of shear wall with concretefilled steel tubular frame and embedded steel plate is relatively better with strong energy dissipating capacity, and it can be used in high-rise buildings; in two specimens, concrete-filled steel tubular frame and steel plates (including embedded steel plates) play a prominent role in energy dissipation.Keywords:concrete-filled steel tubular frame; steel plate; shear wall; shaking table test; elastic-plastic time history analysis
