摘要

摘要:
为提高墙板抗剪性能和装配化程度，研发一种预制填充轻质浆料的冷弯薄壁型钢组合墙板，进行了6片组合墙板的抗剪性能试验，对其破坏特征、荷载-位移关系曲线、承载力、延性进行分析，研究了有无水泥纤维面板、浆料类型、墙板厚度、钢丝网层数等参数对组合墙板抗剪性能的影响。试验结果表明：有无覆板、浆料类型对组合墙板承载力和延性有较大影响，两侧覆有水泥纤维板的墙板承载力可提高74%左右，水泥基浆料-墙板较石膏基-浆料墙板承载力提高38.4%左右；钢丝网层数对组合墙板的抗剪承载力无明显影响，但可以提高墙体延性。

Abstract:
To improve the performances of shear walls and the assembly degrees, a novel type of prefabricated cold-formed thin-wall steel walls filled with light weight polymer mortar (LPM) was developed. The shear performance test for six shear walls were conducted. The failure modes, load-displacement relations, shear capacity, ductility were studied comprehensively. The influence factors including presence or absence of cement-fiber panels, mortar types, wall thickness, and the layers of steel wire gauze were studied. The test results showed that the panels and mortar types had great effect on the failure modes, shear bearing capacity and ductility of shear walls, the panels on both sides could increase the bearing capacity of shear walls by 74%. The bearing capacity of shear walls filled with cement-based LPM could be 38.4% higher than that of walls filled with gypsum-based LPM. The layers of steel wire gauze had no obvious influence on the shear bearing capacity but had a great influence on the ductility of wall panels.
