在我国一些地区,不少三至五层砖混结构民用建筑采用如下形式:每开间皆有横隔墙,外挑悬臂梁承重的外走廊、外阳台,其剖面如图1所示。其悬挑梁的荷载在基础设计中的计算一般按下列三种方法进行:1.不计梁悬臂弯矩的作用,不考虑上部纵横墙的整体连续性,悬臂梁的垂直荷载传给其内伸的横隔墙,由横隔墙按砌体压力扩散角扩散传递至横隔墙的基础;2.悬挑梁的垂直荷载传至梁下纵墙基础;3.悬挑梁垂直荷载一部
In some areas of China, many three-to-five-story civil buildings with brick-concrete structures adopt the following forms: Each opening has a transverse wall, and the external corridor and the outer balcony that bear the weight of the cantilever beam are shown. The section is shown in Figure 1. The calculation of the cantilever beam load in the basic design is generally carried out according to the following three methods: 1. Excluding the effect of beam cantilever bending moments, regardless of the overall continuity of the upper vertical wall, the vertical load of the cantilever beam is transmitted to its internal extension. The transversal partition wall is transmitted from the transversal partition wall to the foundation of the transversal wall according to the diffusion angle of the masonry pressure; 2. The vertical load of the cantilever beam is transmitted to the foundation of the vertical wall under the beam; 3. The vertical load of the cantilever beam
