摘要：本文考虑了组合墙体骨架立柱C型钢截面大小、组合墙体开洞以及墙架角部焊接钢板等研究内容，在内蒙古科技大学土木实验室设计了5个1:2的组合墙体试件，对这些试件进行地震力的模拟，将采集到的数据通过对比分析得到：组合墙体骨架截面尺寸对组合墙体的抗震承载能力的影响比较小，墙体开洞使墙的水平抗剪承载力有所下降，角部焊接钢板使墙体的刚度有所提高，屈服强度提高7.2%，最大荷载提高4.5%，极限荷载提高4.7% ，组合墙体墙板采用兼墙板其承载能力要比采用石膏板的墙体提高一倍左右。

Abstract:The combination wall body frame column C payments section size, combination wall open hole angle and wall frame welding plate were discussed. The civil engineering laboratory of Inner Mongolia university of science and technology designed five 1:2 composite wall specimens.The specimens of earthquake force simulation and the collected data were obtained by means of comparison and analysis. Theeffect of combination wall in composite wall body skeleton on the seismic bearing capacity is small, and an open hole in the wallinfluenced the bearing capacity of the wall,making its horizontal shear smaller. The corner welding steel plate improved the stiffness of the wall, with an increase of 7.2% in yield strength. The maximum load increased by 4.5%, and the ultimate load increased by 4.7%.The bearing capacity of the composite wall panels using wallboard is more doubled than that ofthe plasterboard walls.
