Research on lateral performance of foamed concrete wall panel with built-in column braces

Based on the advantages of inter column braces and foam concrete, a foam concrete wallboard with built-in column braces for structural stress is proposed. In order to study the lateral resistance performance of this kind of wallboard, the numerical analysis model of this kind of wallboard is established by using the general finite element analysis software. Through comparative analysis, the effectiveness of the parameter selection of the finite element analysis model is verified. On this basis, the influence of parameters such as foam concrete strength, steel material and thickness of braces section on the lateral resistance of the wall panels is analyzed. Based on the principle of small deformation superposition, the calculation formula of lateral stiffness of this kind of wallboard is derived and compared with the results of finite element analysis. The research results show that: the wallboard has a large horizontal lateral stiffness, which can greatly improve the lateral resistance performance of steel frame structure, and its approximate calculation method of lateral stiffness and shear bearing capacity has high calculation accuracy, which can be applied to the engineering application of this kind of wallboard.
