摘　　要：在填充墙中设置构造柱是提高砌体结构面外承载力的重要措施,为了解决传统钢筋混凝土构造柱施工复杂、质量无法保证、难以回收利用等缺陷,提出在填充墙中设置方钢管混凝土构造柱,以进一步提高对墙体的约束能力和砌筑结构的安全性。通过对6块填充墙进行平面外加载试验,以分析两种不同构造柱下填充墙缩尺模型的面外承载能力。并采用ABAQUS模拟填充墙的面外极限荷载。试验结果表明,两构造柱的填充墙具有相同的面外受力表现,而方钢管混凝土构造柱较传统构造柱对墙体的约束效果提升了80.3%,面外极限荷载约提升了249.9%。For the structural columns to be set up in fill walls is an important measure to improve the out-of-plane bearing capacity of masonry structures.In order to address such shortcomings as complex construction,quality assurance,and difficulty in recycling in traditional reinforced concrete structural columns,it is proposed to install square steel tube concrete structural columns infill walls for a further improvement of the constraint capacity of the wall and the safety of the masonry structure.Based on the out-of-plane loading tests conducted on 6 fill walls,an analysis is made of the bearing capacity of two scaled models offill walls under different structural columns,followed by a simulation of the out-of-plane ultimate load of thefill walls by using ABAQUS.The experimental results show that thefill walls under the two structural columns are characterzied with the same out-of-plane stress performance,while the confinement effect of the square steel tube concrete structural column on the wall has been improved by 80.3%,and the out-of-plane ultimate load has been increased by 249.9%.
