| 摘 要： | 本文根据砼结构设计规范的抗裂验算规定,提出了计算预应力超静定结构平衡荷载的办法,并据此平衡荷载计算所需预应力钢筋的面积,避免了预应力超静定结构设计中按经验估算平衡荷载值引起的返工重算或不合理配筋。文中附有计算实例。

| Abstract: | Based on the stipulation of check computation of cracking resistance provided in the code for design of concrete structures in China,this paper presents a method for calculating the balanced loads in statically indeterminate prestressed concrete structures. The a-mount of prestressed reinforcement can be determined by these balanced loads.The proposed method can avoid the tedious recalculations or irrational prestressing caused by experimential estimation of the balanced loads in design.Numerical examples are given at the end of the paper. |
