部分予应力混凝土受弯构件最优配筋法

The Optimum Method of Distribution Bar for Partially Pressed Concrete with Flexure

本文根据予应力混凝土受弯构件的受力特征.分析了全予应力、部分予应力及普通混凝土受弯构件在使用阶段的特点。由此提出了设计予应力受弯构件的最优配筋法,根据本文提出的方法,可以设计出满足使用要求的全予应力或部分予应力混凝土受弯构件.

In the paper. the characteristics of the bending members with complte prestressed concrete and partially prestressed concrete and general reinforced concrete were analysed and studied in terms of the beha- viour of prestressed concrete members with flexure. One optimum method for des- igning partially prestressed concrete memders with flexure was put forward. From the method suggested in the paper, the rational design for prestressed or partially prestressed concrete bending, members that meet the need of ser- viceability can be easily obtained and the good economic benifit can be ach- ieved as well.
