摘要
对考虑竖向荷载作用的稀疏竖向加劲钢板剪力墙试件进行了试验和有限元研究,给出了试件的面内面外位移曲线和等效Mises应力曲线,考察了不同大小的竖向荷载对加劲钢板剪力墙性能的影响。研究表明,稀疏竖向加劲钢板剪力墙有较高的初始抗侧刚度和极限承载力,整体失稳后仍能继续稳定地承受荷载,竖向加劲肋应力在区格屈曲前后变化较大,有限竖向荷载对加劲钢板剪力墙的初始刚度基本没有影响,但会降低剪力墙的极限荷载和极限侧移。
The discrete vertical stiffened steel plate shear wall specimen was tested and simulated with gravity loads considered.The stress of shear wall panels and stiffeners were analyzed detailly,and the influences of gravity loads to stiffened steel plate shear wall performance were investigated.The research shows that the discrete vertical stiffened steel plate shear wall has high initial lateral stiffness and ultimate bearing capacity.The steel plate wall can carry loads steadily after overall buckling.The stress of vertical stiffener changes largely after panels buckling.The finite gravity loads have little affects on the initial stiffness of stiffened steel plate shear wall and have some affects on ultimate strength and ultimate displacement of steel plate shear wall.
