| 摘 要： | 应用有限元法对某砌体6层住宅平面进行由温度引起钢筋混凝土屋盖与山墙砌体收缩膨张不均而产生的水平剪力和砌体的抗剪承载力计算，比较烧结砖砌体和单排孔灌孔混凝土砌块砌体的抗剪承载力，从而发现单排孔灌孔混凝土砌块在抵抗温度应力方面的优点。在砌体结构中优先采取灌孔混凝土砌块砌体可以达到减少裂缝的目的。

| Abstract: | The capacity of resistance to horizontal shear and the bearing capacity of shearing resistance of the top of masonry structure under temperature loads are caculated using the finite element method for a 6-layer house planar chart instance and the bearing capacity of shearing resistance of temperature loads between fired common brick masonry and concrete small hollow block masonry are analyzed comparatively. Based on the computation results, this paper finds some advantages of concrete small hollow block masonry in preventing temperature stresses. Therefore ,concrete small hollow block masonry should be pay prior attention for the purpose of reducing the gable cracks. |
