摘要
内置钢板-混凝土组合剪力墙在钢筋混凝土剪力墙截面中配置钢板,充分发挥了钢筋混凝土和钢板的作用,其抗弯、抗剪性能有了明显提高。本文通过ABAQUS有限元软件建立组合墙体的精细化模型进行数值分析,并将模拟结果与试验结果进行对比,验证模型的正确性。随后通过36组模型研究了钢板厚度、混凝土强度和轴压比对组合墙体抗剪承载力的影响。最后结合中国、美国和日本的相关结构设计规范,对内置钢板-混凝土剪力墙的斜截面受剪承载力计算公式提出修改建议。
Steel plate reinforced concrete shear wall consists of steel plate in the reinforced concrete wall.The co-working of the steel plate and reinforced concrete makes a full use of the advantages of both steel and concrete.The flexural and shear behavior of composite shear wall are significantly improved.In this paper,a nonlinear 3-D finite element model in ABAQUS is developed and validated against published experiment results.Then,a parametric study is conducted to evaluate the effects of the parameters on shear strength behavior of composite shear wall,including steel plate ratio,concrete strength,and axial load from 36 finite element models.Finally,a formula of the shear strengths of composite shear wall is proposed according to the Chinese Code JGJ138-2016,USA Code AISC 341-10 and Japan Code AIJ.
