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诸因素,采用正交试验设计,通过对单跨无洞框支密肋壁板结构墙梁有限元计算结果的直观分析和方差分析,对其托梁内力的影响因素进行了显著性分析,并在此基础上利用回归分析得到了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 and height-to-length ratio of the bottom frame column section, the orthogonal design of one-span frame-supported multi-ribbed wall beam without opening was done and the internal forces of the trimmer beam were calculated with the finite element method. Through the visual analysis and variance analysis of the results, the significance analysis of the factors influencing the internal forces of the trimmer beam was done. Then, the internal force coefficients of the trimmer beam are obtained through the regression analysis.
