进行面内荷载作用下低屈服点钢板剪力墙的试验研究。在低屈服点钢板剪力墙结构中,钢板墙采用低屈服点型钢,而边缘框架采用高强型钢。分析了面内单调荷载作用下,低屈服点型钢墙的非线性剪切屈曲性能及宽厚比的影响。对多层低屈服点钢板剪力墙进行滞回性能试验,研究刚度、强度、变形及耗能性能。结果表明:低屈服点钢板剪力墙具有优越的变形及耗能能力,侧向荷载作用下,其层间位移角能超过5%。
Experimental Study on Shear Wall with Low Yield Point under Plane Load. In the low yield point steel plate shear wall structure, the steel wall uses low yielding section steel, and the edge frame adopts high strength steel. The effects of monotonic loading on the nonlinear buckling buckling properties and the aspect ratio of low yield point steel walls are analyzed. The hysteretic behavior of multi-layer low yield point steel plate shear wall was tested to study the stiffness, strength, deformation and energy dissipation. The results show that the low yield point steel plate shear wall has superior deformation and energy dissipation capacity, and the displacement angle between layers can exceed 5% under the lateral load.
