垫梁下面砌体的局部受压强度分析

Local compression analysis for masonry beneath the pad-stone

根据规范规定,大跨度的屋架和梁支承面下的砌体应设置混凝土或钢筋混凝土垫梁.利用钢筋混凝土连续圈梁作为垫梁,可把大梁传来的集中荷载分布到一定宽度的墙体上去.将垫梁进行理论强度受力分析,通过受力分析后,可以合理确定垫梁类型,以便保证墙体合理受载.

Based on the crierion and the regulation,the masonry beneath the roof truss of the big span and the supporting face of the pad?stone should set up concrete or reinforced concrete pad?stone.The reinforced concrete continuous ring beams can be used as the pad?stone.In this way,the concentrated load from the crossbeam will be distributed on the walls with certain breadth.By theoretical local compress analysis for pad?stone,it is considered that the types of pad?stone can be reasonably determined so as to ensure the reasonable load of the walls.
