摘要: 考虑墙梁跨长比、托梁高跨比、墙体高跨比诸因素,采用正交试验设计,通过对双跨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,并考察了墙体洞口位置对托梁内力的影响,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。

Abstract: Considering the factors of span-to-span ratio of the wall beam,height-to-span ratio of the trimmer beam and height-to-span ratio of the wall,the orthogonal design of two-span frame-supported multi-ribbed wall beam is done and the internal forces of the trimmer beams are calculated with finite element method.Through the visual analysis and variance analysis of the results,the significance analysis of the factors influencing the internal force of the trimmer beam is done,and the influence of the opening position in the wall is also studied.Then,the internal force coefficient of the trimmer beam is obtained through regression analysis
