型钢混凝土剪力墙抗震性能研究

Research on Seismic Performance of Steel Reinforced Concrete Shear Walls

为研究型钢混凝土剪力墙结构的抗震性能,应用ABAQUS有限元分析软件建立了普通剪力墙SRC-0、内置于剪力墙暗柱内的模型SRC-1、内置与墙身的模型SRC-V和SRC-X。在低周往复作用下,分析了不同内置形式之间的抗震性能差异。结果表明,内置型钢混凝土剪力墙初始刚度得到提升,极限承载能力相比于对照组SRC-0均有不同程度的提高,抗侧移能力和耗能能力得到一定程度的提升,内置型钢明显改善了普通剪力墙的抗震性能。

To investigate the seismic performance of steel reinforced concrete(SRC)shear wall structures,finite element analysis software ABAQUS was utilized to establish models including an ordinary shear wall(SRC-0),a model with SRC embedded within the hidden columns of the shear wall(SRC-1),and models with SRC embedded within the wall body(SRC-V and SRC-X).Under low-cycle reversed loading,the differences in seismic performance among different embedment forms were analyzed.The results indicate that the initial stiffness of the SRC shear walls was enhanced,with varying degrees of improvement in ultimate load capacity compared to the control group(SRC-0).The lateral load resistance and energy dissipation capacity were also improved to some extent.The embedment of steel shapes significantly enhanced the seismic performance of ordinary shear walls.
