陶粒砼剪力墙的试验研究

Experimental Study of Ceramsite Concrete Shear Walls

本文介绍8片陶粒砼剪力墙试件与4片普通砼剪力墙试件的对比试验研究结果,讨论了在低周反复荷载下单肢剪力墙的破坏形态、变形能力、构件延性,斜截面抗剪强度及水平和竖向分布钢筋的配筋构造等,证实了在低轴压比下的陶粒砼剪力墙可以满足延性要求,最后对轻砼剪力墙斜截面承载力计算与其配筋构造提出了一些设计建议。

This paper presents the comparative test results of 8 pieces of ceramsite concrete shear walls and 4 pieces of common concrete ones. In which, the collapse patterns, deformation capability, ductility, shear strength of inclined sections of single-limb ceramsite concrete shear walls under low cyclic reversed loading as well as the details of horizontal and vertical reinforcement have been discussed. Through experiments, it is proved that the ceramsite concrete walls at low axial load level can satisfy the demand of ductility. Finally, design recommendations for calculating shear strength of inclined sections in lightweight concrete shear walls and the details of reinforcement arc put forward.
