摘要
为更好发挥减震围护墙对装配式钢框架单元力学性能的有利作用,采用ABAQUS软件建立了13个装配式钢框架-减震围护墙单元有限元模型,研究不同上、下层墙板单元高度比、减震层摩擦系数、墙板材质对框架单元的力学性能的影响及其规律,并给出有关减震围护墙设计的建议。研究结果表明:增加上、下层墙板单元高度比、提高减震层摩擦系数和增大墙板材质密度均可一定程度提高框架的屈服荷载和水平承载力,且不会明显增加框架的刚度。因此,设计时可根据洞口尺寸需求尽量选取较大的上、下层墙板单元高度比,且当开设窗洞时,建议将窗洞设置在上层墙板单元。同时建议选取摩擦系数较大的材料制作减震层,并选用材质密度相对较大的墙板。
In order to give full play to the beneficial effect of damped enclosure wall on the mechanical properties of prefabricated steel frame,thirteen finite element models of prefabricated steel frame-damped enclosure wall(PSF-DEW)were established by ABAQUS software.The effects and rules of the height ratio of wall panels,friction coefficient of damping layer,wall panel material on the mechanical properties of PSF-DEW were studied and suggestions about the design of DEW were given.The results show that,the yield load and lateral bearing capacity of the frame can be increased to a certain extent by increasing the height ratio of wall panels,increasing the friction coefficient of damping layer and increasing the material density of the wall panels,while the stiffness of the frame is not significantly increased.Therefore,the height ratio of wall panel can be selected as far as possible according to the size of the opening.When setting the window opening,it is suggested to set the window opening in the upper wall panel.At the same time,it is suggested to select a material with a large friction coefficient to act as the damping layer,and select a wall panel with a relatively large material density.
