摘要:

为研究钢带加强螺钉孔对冷弯型钢组合墙体抗震性能的影响,对3个冷弯型钢组合墙体足尺试件进行低周反复加载试验,分析该加强形式对冷弯型钢组合墙体的破坏模式、侧向刚度、承载能力、延性以及耗能性能的影响。同时采用有限元软件OpenSEES对墙体进行数值分析。结果表明:钢带加强螺钉孔型冷弯型钢组合墙体的破坏形式仍然为螺钉连接失效和板缝滑移,钢带能够使覆面板的螺钉连接处得到加强,从而提高组合墙体的抗侧刚度和受剪承载力; 与螺钉孔未进行钢带加强的墙体试件(HS-140-A)相比,2个加强式的组合墙体试件(HS-140-B,HS-140-C)受剪承载力分别提高了32.5%,58.1%,抗侧刚度分别提高了31.7%,59.3%; 螺钉孔由钢带加强后,墙体试件的耗能性能显著提升; 3个试件的延性系数均大于8,呈现出良好的变形能力; 有限元模型能反映螺钉连接非线性行为对墙体滞回性能的影响,有限元分析结果与试验结果的相对误差控制在10%以内,模型具有较好的精度。

Abstract:

In order to study the impact of strengthened steel strips in screw holes on seismic behavior of cold-formed steel(CFS)framing walls, three full scale specimens of CFS framing walls were tested subjected to low cyclic loads. The influence of the strengthening form on the failure mode, lateral stiffness, bearing capacity, ductility and energy dissipation performance of CFS framing walls was analyzed. The finite element software OpenSEES was used for the numerical analysis of the wall. The results show that the failure mode of the cold-formed steel framing walls with strengthened steel strips in screw holes is still screw connection failure and sheathing seam slip. The steel strip can strengthen the screw connection of the cladding panel, so as to improve the lateral stiffness and shear capacity of the composite wall. Compared with the specimen without steel strip reinforcement in screw hole(HS-140-A), the shear capacity of the strengthened specimens(HS-140-B, HS-140-C)is improved by 32.5% and 58.1%, and their lateral stiffness is increased by 31.7% and 59.3%. The energy dissipation capacity of the specimens was significantly improved after enhancement of screw holes by the steel strips. The ductility coefficients of the three specimens are greater than 8, which shows good deformation ability. The finite element models can represent the effect of screw connections nonlinear behaviour on hysteretic performance of the walls. The relative error between the finite element analysis results and the experimental data is controlled within 10%, and the model has good accuracy.
