对结构工程中普遍存在的大跨度混凝土梁、板挠度过大的质量通病进行了分析,提出在结构施工图设计中有效控制大跨度梁、板挠度的方法。通过工程实例,对已经出现过大挠度的混凝土梁、板提出合理的处理方法,供结构设计人员参考。
The common problems of mass deflection of large span concrete beams and slabs in structural engineering are analyzed, and the method of effectively controlling the deflection of long span beams and slabs in the construction drawings design is proposed. Through the engineering examples, reasonable treatment methods are proposed for the concrete beams and slabs that have appeared the large deflection for the reference of the structural designers.
