摘　　要：为研究不同钢板、CLT厚度对钢夹板-正交胶合木组合剪力墙的破坏形式及轴压性能影响,文中设计5组不同钢板厚度、CLT厚度的钢夹板-CLT组合剪力墙进行轴压试验,并对试验中观察到试件的变形发展过程、破坏模式以及所得到的荷载-位移曲线、侧向挠度变化、应变变化、承载能力等进行分析。研究结果表明,5个试件均为失稳破坏,由于试件构造相同且均由螺钉连接,所以破坏过程均出现钢板发生面外局部屈曲、横向贯通鼓曲、螺钉崩开,导致试件发生失稳破坏,丧失承载能力。钢板厚度以及正交胶合木厚度的增加均有效提高了试件承载能力,而钢板对于墙体承载力的提升更为明显。研究可为钢木组合结构及剪力墙发展提供参考。To investigate the effects of different steel plate and CLT(Cross-Laminated Timber)thicknesses on the failure modes and axial compression performance of steel plate-CLT composite shear walls,five groups of composite shear walls with varying steel plate and CLT thicknesses were designed for axial compression tests.The study analyzes the deformation development process,failure modes,load-displacement curves,lateral deflection changes,strain variations,and bearing capacities observed during the tests.The results show that all five specimens failed due to instability.Since the specimens had identical structures and were connected by screws,the failure process involved local out-of-plane buckling of the steel plate,transverse bulging,screw pullout,and ultimately instability and loss of bearing capacity.The increase in both steel plate and CLT thicknesses effectively improved the specimens'bearing capacity,with the steel plate thickness having a more significant impact on the wall's bearing capacity.This research provides valuable insights for the development of steel-wood composite structures and shear walls.
