輕型鋼木組合剪力墻抗側(cè)性能試驗(yàn)研究
[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.
