【摘要】 钢框架双钢板内填混凝土组合剪力墙是一种新型的双重抗侧力结构体系。应用ABAQUS有限元软件,对12片钢框架双钢板内填混凝土组合剪力墙进行抗剪性能研究。通过改变混凝土墙板厚度、钢板厚度、混凝土强度、剪跨比等参数分析钢框架和组合剪力墙的剪力分配,并提出双钢板内填混凝土组合剪力墙的抗剪承载力计算公式。结果表明:在峰值点时,剪力墙承担总剪力的70%~90%,说明剪力墙是主要的抗侧力构件;将提出的抗剪承载力计算公式与有限元模拟结果对比,结果吻合得较好,说明所提出的公式合理。更多还原

【Abstract】 A steel frame with Bi-steel-plate composite shear wall infilled concrete is a new type double resis-tance to the lateral force structure system. Twelve steel frames with Bi-steel-plate composite shear walls infilled concrete were simulated to study the resisting shear performance by the finite element software ABAQUS. The ef-fects of the concrete slab thickness, the steel plate thickness, concrete strength and shear span ratio on the shear distribution for steel frames and composite shear wall were analyzed, and the calculation formula of the shear ca-pacity was proposed. Results showed that the shear wall undertook 70%~90% of the total shear at the peak point,which explained the shear wall was the main component to resist the lateral force. The proposed formula for cal-culating the shear also agreed with the finite element simulation results, which showed that the proposed formula was reasonable.更多还原
