摘要
为对比悬挂式预制混凝土墙板框架与纯钢筋混凝土框架和普通砌体填充墙框架的抗震性能,采用有限元分析软件ABAQUS分别建立了3种结构模型,并对其进行反应谱分析以及时程分析。通过反应谱分析得出模型的基底剪力、楼层位移、层间位移角和最大应力位置等,通过时程分析得出基底剪力、顶点位移以及应力随时间变化等。分析结果表明:悬挂式预制混凝土墙板框架比纯钢筋混凝土框架和普通砌体填充墙框架具有更好的抗震性能,墙板部位的破坏程度比普通砌体填充墙轻;墙体对框架结构的影响比较大,不合理布置墙体容易导致框架结构出现薄弱层,对抗震极为不利,建议对框架结构进行设计时应该充分考虑墙体的影响。
This paper compares the seismic performance of pure reinforced concrete frame,frame with hanging connection and frame using ordinary masonry infill walls. The response spectrum analysis and time history analysis were performed in ABAQUS. The base shear,the story displacement,the story drift ratio and the location of maximum stress in the response spectrum analysis and time history analysis were discussed. The analyses show that the frame with hanging connection has the better seismic performance than the frame using ordinary masonry infill walls and the damage of the precast concrete infill walls is less than that of the ordinary masonry infill walls. The analyses also indicate that the infill wall's influence on the frame structure is significant. Unreasonable arrangement of infill walls easily leads to the weak layer of the frame structure,which is very adverse to the seismic performance of the frame. So the effect of infill walls should be fully considered in the design of frame structures.
