Analysis of Lateral Resistanceotf Wood-Plasterboard Composite Shear Wall

文中就面板材料、面板厚度以及剪力墙尺寸对木结构-磷石膏板剪力墙承载力、抗侧刚度、屈服性能以及延性的影响进行研究。结果表明,纸质石膏板-剪力墙的抗剪强度比磷石膏板-剪力墙的抗剪强度低10.3%,抗侧刚度低13.7%,屈服荷载低2.5%,延性系数提升9.8%;剪力墙施加竖向荷载后,其抗剪强度提升24.5%,抗侧刚度下降26.8%,屈服荷载提升30.1%。上述研究成果可为木结构-磷石膏板剪力墙的结构优化设计提供参考。

In this paper,the effects of panel material,panel thickness and shear wall size on the bearing capacity,lateral stiffness,yield performance and ductility of wood-phosphor plasterboard shear walls are studied.The results show that the shear strength of paper plasterboard shear wall is 10.3%lower than that of phosphorus plasterboard shear wall,the lateral stiffness is 13.7%lower,the yield load is 2.5%lower,and the ductility coefficient is 9.8%higher.When vertical loads are applied to shear walls,the shear strength increases by 24.5%,the lateral stiffness decreases by 26.8%,and the yield load increases by 30.1%.The above research results provide a certain reference for the structural optimization design of wood-plasterboard shear wall.
