| 摘 要： | 通过对不同比例模型框支密肋壁板结构墙梁在单调竖向荷载作用下的试验,对墙梁在竖向荷载作用下的受力特点给予探讨;结合有限元分析,对影响墙梁内力分布的主要因素进行研究;以弹性地基梁理论为基础,采用三角级数解析,给出框支密肋壁板结构墙梁内力计算公式,并回归出内力修正系数。理论分析和试验结果表明,托梁与密肋复合墙体具有相当强的组合作用;采用本文提出的内力计算公式进行计算更接近试验结果。

| Abstract: | Based on the experimental study on different scaled models of the frame-supported multi-ribbed slab wall beam under monotonously vertical load,it is discussed the mechanical behavior of the wall beam under vertical load.Moreover,the main factors affecting the internal force distribution are studied by means of finite element analysis.According to the theory of elastic foundation beam and quoting the trigonometric series analysis,the internal force calculation formula of the frame-supported multi-ribbed wall beam is put forward,and the internal force correction coefficient in the formula is obtained by regression analysis at the same time.Theoretical analysis and experimental results show that there has strong combination action between the trimmer beam and multi-ribbed composite wall,and the results calculated by the practical internal force calculation formula can be closer to the experimental values. |
