为有效提高开设洞口的EPSC格构式混凝土墙在实际工程中的水平承载能力,应用大型有限元分析软件ANSYS建立12个格构式墙体模型,以洞口形式、洞口位置及洞口大小为设计参数,在单调载荷作用下,对其水平承载能力进行分析.研究结果表明:洞口的出现会使EPSC格构式混凝土墙的水平承载能力明显减小,洞口截面积越大,其水平承载能力越低;洞口总截面积相同时洞口数量对墙体的水平承载力影响不大,但洞口数量越多,承载力越低;洞口截面积相同,随洞口位置距离墙体中心距离增大,墙体极限载荷也有所提高.
In order to effectively improve the horizontal bearing capacity of EPSC latticed concrete walls with openings in actual projects, 12 grid-type wall models were created using the large-scale finite element analysis software ANSYS. The design parameters were the shape of the openings, the location of the openings and the size of the openings. Under the monotonous load, the horizontal carrying capacity is analyzed. The results show that: the appearance of the opening will significantly reduce the horizontal carrying capacity of the EPSC lattice concrete wall. The larger the cross-sectional area of the hole, the lower the horizontal carrying capacity. When the total cross-sectional area of the hole is the same, the number of openings has little effect on the horizontal bearing capacity of the wall, but the more the number of openings is, the lower the bearing capacity is; the cross-sectional area of the opening is the same, and the distance from the opening to the center of the wall increases. The load has also increased.
