【摘要】：对轻型钢木组合剪力墙抗侧性能进行研究,设计一个轻型钢框架对比试件,进行单调加载试验;两个轻型钢木组合剪力墙试件,进行低周反复荷载试验;考察有无OSB板及板厚对轻型钢木组合剪力墙抗侧性能的影响,研究墙体的破坏形态、抗侧承载力、滞回性能、延性、耗能能力等.研究结果表明,轻钢龙骨框架中引入常用的OSB板组成轻型钢木组合剪力墙可提高其侧向承载能力,随着板厚的增加抗侧性能有所提升;轻型钢木组合剪力墙抗震性能较差,轻钢龙骨框架与OSB板未能良好地协同变形发挥其组合作用,可见自攻螺钉未能起到较好的连接作用.建议进一步深入探究其协同工作机理及覆面板材料和厚度等参数的影响规律,为轻型钢木组合剪力墙工程实际提供参考.
[Abstract]:In this paper, the anti-lateral performance of light-duty steel-wood composite shear wall is studied, and a contrast specimen of light steel frame is designed to carry out monotonic loading test, and two light-duty steel-wood composite shear wall specimens are tested under low-cycle cyclic loading. The effects of OSB plate and thickness on the lateral resistance of light-duty steel-wood composite shear wall were investigated, and the failure pattern, lateral bearing capacity, hysteretic performance, ductility and energy dissipation capacity of the wall were studied. The results show that the lateral load-bearing capacity of light-weight steel-wood composite shear wall can be improved with the increase of plate thickness, and the seismic performance of light-weight steel-wood composite shear wall is poor with the increase of plate thickness, and the commonly used OSB plate is introduced into the light steel keel frame to form light steel-wood composite shear wall. The combination of light steel keel frame and OSB plate was not well combined, so the self-tapping screw could not play a better connection role. It is suggested that the synergistic working mechanism and the influence law of the parameters such as overlay material and thickness should be further explored so as to provide a reference for the engineering practice of light-duty steel-wood composite shear wall.
