目的研究板-柱结构的抗震性能，推广其在抗震区应用．方法采用三维实体单元建模，对柱网及柱截面尺寸相同的板-柱结构及框架结构进行pushover分析及非线性时程分析．结果通过pushover分析，得到了结构的基底剪力-顶点侧移关系曲线及能力曲线，构造了弹塑性反应谱并以此求出结构的目标位移，研究了结构的出铰机制，对比了各加载阶段的结构响应；通过非线性时程分析，给出了结构的基底剪力及顶点侧移时程曲线，塑性铰出铰及能量耗散情况，并将不同地震波激励下的结构侧移与pushover分析结果进行了对比．结论设计合理的板-柱结构可用于Ⅱ类场地7度抗震设防区．

英文摘要：

The purpose of this paper is to research on seismic behavior of plate-column structure and popularize it in seismic region. With the method of creating structural models by three-dimensional solid element and pushover analysis and nonlinear time-history analysis of the two structures （plate-column structure and frame structure） with the same column layout and section size. With the pushover analysis, curves of base shear versus top drift were offered;plastic spectrum was obtained;the target displacement was calculated by it; failure mechanism was researched and earthquake responds of each phase were compared. With the nonlinear time-history analysis, time-history curves of base shear and of top drift, plastic hinges distribution and energy dissipation were offered. Drifts subjected to different earthquake waves and the results of pushover analysis were compared. The conclusion is brought forward that the plate-column structure designed suitably can be built in the second soil site seismic fortification areas of 7 degree.
