摘要
为解决工程中日益增多的大跨度框架结构设计,对部分预应力单跨框架的计算做了较详细的介绍,主要内容有曲线预应力筋的布置、预应力损失和预应力引起的内力计算以及抗裂验算和挠度验算等。
In order to solve the desing problems encountered increasingly of large-span framed structure in engineering,it is introduced detailed for calculating partially prestressed reinforced concrete single-span framed struture.The main points are the arrangement of curved steel tendons,the loss of prestressing force,the calculation of internal force caused by prestressing force,the caculation of crack resistance and deflection etc.
