摘要
本文基于名义拉应力控制裂缝宽度的原理以及正截面承载力分析，建立了用拉应力限制系数来控制裂缝宽度的计算模式，从而简化了设计计算。
In this paper,a method of controlling crack-widths of partially prestressedcoocrete structures by a restrictive coefficient of tensile stress is established based on theprinciple of controlling crack-widths with nominal tensile stress and the ultimate strengthanalysis to simplify the design process.
