| 摘 要： | 建立了框支密肋复合墙体墙梁的力学简化模型，并利用考虑水平摩阻力的弹性地基梁法进行托梁内力计算，同时应用有限元程序对算例进行数值对比分析。理论研究与计算分析表明：框支密肋复合墙体墙梁考虑墙体与托梁之间的界面剪力是必要的，否则不能充分体现托梁与墙体的组合工作性能，内力计算误差较大。

| Abstract: | The simplified mechanical model was proposed for frame-supported multi-ribbed composite wall beam. And the internal force of joist was calculated with the method of beam on the elastic foundation which takes the horizontal friction resistance into consideration. Moreover, a comparative analysis was employed with FEA program. It was found that it was necessary to consider the interfacial shearing force between wall and joist for the frame-supported multi-ribbed composite wall beam, otherwise, the performance of the composite would not exhibited sufficiently and the calculation error would be large. |
