摘　　要：考虑托梁高跨比、墙体高跨比、底部框架柱的截面高度与其长度之比、墙体洞口位置诸因素,采用正交试件设计,对单跨带洞框支密肋壁板结构墙梁中洞口对托梁内力的影响进行了分析,进而通过回归分析得到了单跨带洞框支密肋壁板结构墙梁考虑墙梁组合作用的托梁内力系数。Considering the factors of height-to-span ratio of the trimmer beam, height-to-span ratio of the wall, section beight-to-length ratio of the bottom frame column and the position of the opening in the wall, the orthogonal design of single-span frame-supported multi-fibbed wall beam with opening is done and the influence of the opening on the internal force of the trimmer beam is analyzed. Then, the internal force coefficients of the trimmer beam are obtained through the regression analysis.
