双钢板组合剪力墙是一种新型抗侧力构件,它综合了钢板剪力墙和混凝土剪力墙的优点。较高的抗侧刚度、极限承载力、良好的延性和耗能能力使其具有广泛的工程前景。然而在实际施工过程中,通常将外侧钢板作为模板,连续多层浇筑混凝土。采用ABAQUS建立数值分析模型,研究了施工过程中的钢板平面外初始变形和钢板初始压应力对组合剪力墙抗震性能的影响。数值分析结果表明,钢板平面外初始变形和钢板初始压应力均会在一定程度上降低剪力墙的极限承载力和延性。最后给出了控制施工过程中钢板平面外初始变形和钢板初始压应力的建议。
Double steel composite shear wall is a new type of anti-side force components, which combines the advantages of steel shear walls and concrete shear walls. High lateral rigidity, ultimate bearing capacity, good ductility and energy dissipation make it have a wide range of engineering prospects. However, in the actual construction process, the outer steel plate is usually used as a template to continuously pour the concrete in multiple layers. The numerical analysis model was established by ABAQUS to study the influence of initial out-of-plane deformation and initial compressive stress on the seismic behavior of composite shear walls during construction. The numerical results show that both the initial out-plane deformation and the initial compressive stress of the steel plate will reduce the ultimate bearing capacity and ductility of the shear wall to a certain extent. Finally, some suggestions are provided to control the initial out-of-plane deformation and the initial compressive stress of the steel plate in the construction process.
