摘要
本文基于名义拉应力法的基本原理，结合各类结构的理论研究与分析，考虑次内力和外荷载对结构抗裂性能的影响，进而给出了各类预应力混凝土结构正截面裂缝控制的统一计算方法，依据本文方法进行各类结构设计，设计简便、可靠。
Based on the fundamental principle of methed of nominal tension sbo, and cabining with theorehc research and analysis of different sturc, this paper studies the effects of seconds interior force and external load on the ability of crack resistance of structures. Fultheere, a computing method of crack contion of normal section for different strucs is provided. The rnethed in the paper can make design of presbessed concrete structures convenient and reliable.
