摘要
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。
Super deflections in large span concrete beam or slab widely exist in the structural engineering, which is a common quality problem. Methods to control the deflection of large span beams and slabs effectively in structural construction documents design were proposed. Through real project cases, rational methods to solve the existing super deflections in concrete beams or slabs were put forward for references.
