摘要
砼新规范(GBJ10—89)仅提供了按Mu≥M_(cr)控制条件验算P_(pmi)的方法,由于这种方法只能用于截面校核计算,而且计算很繁复。本文在原控制条件基础上推导出的P_(pmin)的选代公式并以此为基础,对影响P_(pmin)计算的诸因素作较全面的计算分析后,提出了P_(pmin)
In the new design code[GBJ10-89] ,M≥Mcr is stipulated as the Control provision of minimum steel ratio Ppmin of prestressed and partially prestressed concrete bar. This criterion can only be used for checking and is Considerably complicated in doing so. However, on the basis of analysis of all the factors which affect the determination of Ppmin, a quite simple Calculating method has been derived.
