摘要:

为研究双波形钢板剪力墙的滞回性能,利用有限元软件ABAQUS分别建立单波形钢板剪力墙与双波形钢板剪力墙的有限元模型,对2种波形钢板剪力墙在低周往复荷载作用下的受力机制及滞回性能进行对比分析,研究了内嵌波形钢板的设计参数对双波形钢板剪力墙滞回性能的影响规律,给出了波形钢板设计参数的取值建议。结果表明:与单波形钢板剪力墙相比,双波形钢板剪力墙的抗侧刚度、承载能力及耗能能力均提高,但其延性有一定程度的降低; 内嵌波形钢板的厚度与波形几何尺寸是影响双波形钢板剪力墙滞回性能的关键参数,随着厚度的增大,双波形钢板剪力墙的抗侧刚度、承载能力、耗能能力及延性均提高; 随着波长的增加,双波形钢板剪力墙的抗侧刚度提高,但承载能力及耗能能力降低; 随着波幅的增加,双波形钢板剪力墙的抗侧刚度降低,但承载能力及耗能能力均提高。

Abstract:

To study the hysteretic performance of double-corrugated steel plate shear wall, the finite element models of single corrugated steel plate shear wall and double-corrugated steel plate shear wall were established by using the finite element software ABAQUS. The stress mechanism and hysteretic performance of the two kinds of corrugated steel plate shear walls under low cyclic loads were compared and analyzed. The influence of the design parameters of the embedded corrugated steel plate on the hysteretic performance of the double-corrugated steel plate shear wall was studied, and the recommended values for the design parameters of the corrugated steel plate were given. The results show that the lateral stiffness, bearing capacity and energy dissipation capacity of double-corrugated steel plate shear walls are improved, but the ductility decreases to a certain extent compared to single corrugated steel plate shear wall. The thickness of corrugated steel plate and geometric parameters of corrugation are key parameters that affect the hysteretic performance of double-corrugated steel plate shear wall. With the increase of thickness of corrugated steel plate, the lateral stiffness, bearing capacity, ductility and energy dissipation capacity are all improved. With the increase of length of trapezoidal corrugation, the lateral stiffness of the double-corrugated steel plate shear wall is improved, and its bearing capacity and energy dissipation capacity decrease. As the amplitude of corrugation increases, the lateral stiffness of the double-corrugated steel plate shear wall decreases while its bearing capacity and energy dissipation capacity are both improved.
