为了研究CCA板填充墙钢框架的受力性能和破坏机理,利用有限元软件ABAQUS对CCA板填充墙钢框架试件,设置两条中间竖缝的CCA板填充墙钢框架试件,设置两条边缝的X形CCA板填充墙钢框架试件和纯钢框架试件进行了低周反复荷载作用下的模拟分析,对这4个试件的破坏特征、滞回性能、延性、刚度和耗能等方面进行了研究。有限元结果表明:CCA板填充墙的不同构造措施会影响墙板裂缝的分布,CCA板填充墙采用两条边缝的X形构造和两条中间竖缝的构造都能缓解墙板的应力集中,减少墙板的开裂;与常规构造相比,结构滞回性能、延性、初始刚度和耗能系数受设置两条边缝的X形构造的影响较小,受设置两条中间竖缝的构造影响较大。研究成果可为带CCA板填充墙钢框架结构的应用提供理论依据。
In order to study the mechanical behavior and failure mechanism of the steel frame with CCA slab wall, finite element software ABAQUS was used to fill the CCA slab wall steel frame test piece with two CCA slab-filled steel frame specimens, The side-seam X-shaped CCA infill wall steel frame specimens and the pure steel frame specimens were subjected to low-cycle repeated load simulation analysis. The failure characteristics, hysteretic properties, ductility, stiffness and loss of these four specimens Can and other aspects of the study. Finite element results show that the different construction measures of the CCA filled wall affect the distribution of the crack in the wall. The X-shaped structure with two side slits and the construction of two middle vertical slits in the CCA filled wall can alleviate the stress concentration , Which can reduce the cracking of the wall panels. Compared with the conventional structure, the structural hysteretic behavior, ductility, initial stiffness and energy dissipation coefficient are less affected by the X-shaped structure with two side seams, and the structure with two intermediate vertical seams Greater impact. The research results can provide a theoretical basis for the application of steel frame structure with CCA filled wall.
