控制预应力混凝土构件的裂缝的目的是确保构件正常使用,对规范控制裂缝的方法进行了分析,介绍了名义拉应力控制预应力混凝土受弯构件裂缝的方法,给出了计算允许名义拉应力的算式,并给出算例。
The purpose of controlling the cracks in prestressed concrete components is to ensure the normal use of components and to analyze the method of regulating cracks. The method of nominal tensile stress for controlling the crack of prestressed concrete flexural members is introduced. The calculation of allowable nominal tensile stress Formula, and gives the example.
