摘　　要：在试验研究的基础上,本文建立了带暗支撑短肢剪力墙结构的弹塑性时程分析力学模型。运用DRAIN2D+程序,对带暗支撑短肢剪力墙结构及普通短肢剪力墙结构进行了弹塑性地震反应时程分析,对二者计算的结果进行了比较。计算分析表明,带暗支撑短肢剪力墙结构的地震反应,明显小于不带暗支撑的普通短肢剪力墙结构。Based on experimental research, an element model for elastoplastic seismic response analysis of RC short-pier shear wall structure with concealed bracings was proposed. Elastoplastic finite element history-time analysis of short-pier shear wall structures with concealed bracings and without ones were carried out. The calculated results of short-pier shear wall structures with concealed bracings were compared with those of common short-pier shear wall structures without concealed bracings. The calculated results show that the seismic response of short-pier shear wall structure with concealied bracings is smaller than that of common short-pier shear wall structure.
