钢筋混凝土屋面大梁、楼盖梁、屋架等构件支承在砖砌体(墙或柱)上,其支座压力通过砖砌体的局部截面传给墙或柱。这与砖砌体的轴心受压和偏心受压的承载力计算有所不同,原因是砌体的局部受压承载力要比砌体受压承载力为高。为什么?这是因为:支座压力只作用在砌体的局部范围内,而周边未受到局部压力的部份,则像一个套箍一样,箍住砌体的局部受压部份,限制了后者的横向变形,使局部受
Reinforced concrete roof girders, floor beams, roof trusses and other components are supported on a brickwork (wall or column), and its bearing pressure is transmitted to the wall or column through the partial cross section of the brickwork. This is different from the calculation of bearing capacity of axial stress and eccentric compression of brick masonry. The reason is that the local compressive bearing capacity of masonry is higher than masonry compressive bearing capacity. Why? This is because: the seat pressure only acts within the local area of the masonry, and the part without the partial pressure on the periphery, like a ferrule, hoop the local pressure part of the masonry, limiting the rear The lateral deformation of the
