摘要
对无粘结预应力钢筋和有粘结非预应力钢筋的性能进行了分析,归纳了现有设计规范或建议的无粘结部分预应力混凝土梁的裂缝宽度计算公式,并对其中的一些系数等加以比较,以探求一个尽可能符合实际的通用的裂缝宽度计算方法。
Performances of unboned prestressed tendons and bonded nonprestressed tendons are analyzed. Caleulation formula of crack width of unbonded partial prestressed concrete beam in present design code is summarized. Comparative analysis is also made for some parameters＇ setting in order to find a proper and general ealeulation method of eraek width.
