摘　　要：针对已有水平荷载作用下板柱结构等代梁宽度系数的研究进行总结,对比分析了已有研究成果存在的优缺点。通过对板柱结构在弹性阶段水平荷载作用下的等代梁宽度系数进行理论分析,采用ABAQUS有限元软件进行模拟分析,针对水平荷载作用下板柱结构等代梁宽度系数进行了修正;基于对板柱结构在弹塑性阶段下等代梁宽度系数的探讨,修正了已有研究所提出的板开裂弯矩中的截面抵抗矩塑性系数。Previous research on the equivalent beam width coefficient of the slab-column structure under the action of the horizontal load was summarized.The advantages and disadvantages of the existing studies were discussed.Finite element software of ABAQUS was used to simulate and analyze the width coefficient of the equivalent beam for slab-column structures under the horizontal load in the elastic status,and the equivalent beam width coefficient was modified.By discussing the equivalent beam width coefficient of the slab-column structures in the elastic-plastic stage,plastic moment-resistance coefficient of the cross-section in the slabcolumn structures under the cracking moment was modified based on the previous studies.
