本文绘出18个墙梁实验研究结果,讨论了墙梁组合结构的受力特性和破坏形态。通过有限元计算进一步分析了墙梁界面应力状态和托梁内力变化规律。给出了强度计算公式和设计建议。供修订砌体结构设计规范参考和在设计中试用。
This paper draws the results of the experimental study of 18 wall beams and discusses the stress characteristics and failure modes of the wall-beam composite structures. The finite element method is used to further analyze the stress state of the interface between the wall and the beam and the internal force of the joist. Gives strength calculation formulas and design suggestions. The revised masonry structure design specification is referenced and used in the design.
