内填混凝土双钢板组合剪力墙结构是一种新型的抗侧力体系,为了研究钢框架和组合剪力墙的刚度匹配,应用ABAQUS有限元软件分析了三层组合剪力墙在倒三角荷载作用下的滞回性能,通过改变组合剪力墙的跨度和厚度,得到不同的刚度特征值,分析刚度特征值取值对框架及组合剪力墙受力的影响,得到最佳的刚度特征值范围。根据刚度特征值取值范围,得到组合剪力墙墙厚计算公式。分析结果表明,刚度特征值是影响钢框架组合剪力墙结构受力状态和变形特征的主要因素,当刚度特征值取值在1.43~3.27时,钢框架和组合剪力墙刚度比较匹配,结构的受力状态较好。
In order to study the stiffness matching of steel frame and composite shear wall, ABAQUS finite element software is used to analyze the effect of three-layer combined shear wall on the inverted triangular load By varying the span and thickness of the composite shear wall, different stiffness eigenvalues are obtained, and the influence of the stiffness eigenvalue on the force of the frame and the composite shear wall is analyzed to obtain the best stiffness eigenvalue range. According to the range of the characteristic value of the stiffness, the calculation formula of combined shear wall thickness is obtained. The results show that the stiffness eigenvalue is the main factor that affects the stress state and deformation of the composite shear wall structure. When the stiffness characteristic value is between 1.43 and 3.27, the stiffness of the steel frame and the composite shear wall are compared and the stiffness The state of stress is better.
