带壁柱砖墙上大梁垫块尺寸分析

Analysis on Size of Padding Block Under Beam End and on Pilastered Brick Wall

对带壁柱砖墙上大梁垫块的平面尺寸分析计算结果表明,增大与大梁跨度垂直方向的垫块长度对增大局部承载力比较有效。建议当有必要时可采用T形平面形状的垫块,以满足垫块下砌体局部受压承载力的要求,并给出了具体的计算方法及算例供参考。

The size of padding block under beam end and on pilastered brick wall is analysed. The calculating results show that, enlargement of the size of rectangular padding block in the direction perpendicular to the beam span is effective to increase the local compression strength of pilastered brick wall. It is suggested that the T-sized padding block may be used when rectangular padding block is not satisfactory.
