摘要
从预加应力,预应力钢筋与混凝土相应阶段的应力状态出发,对混凝土结构设计规范(GBJ10─89)中先张法构件预加应力产生的法向应力计算公式(3.4.5─1)的来源详尽的论证。
Based on the corresponding stress conditions of the prestressed reinforced and concrete in each stage which is loaded,the source of the normal stress calculating formula(3.4.5-1) in the Design Code of Concrete Structures(GBJ10-89) for the pre-tensioning concrete members is discussed detailly.
