摘要
通过现场实测2根27m采用金属波纹管套管的预应力梁的总摩擦损失,根据《混凝土结构设计规范》给出的公式,反推摩擦系数k、μ值,以此来推断张拉过程中k、μ的变化规律,以及《混凝土结构设计规范》给定值的合理性;根据计算分析,总结现场施工时需注意的关键问题。
Through field test two 27 m of the total friction loss metal bellows sleeve prestressed beams, according to the formula given in the specification, reverse thrust friction coefficient k, μ value, in order to infer the tension during the two values the key question when calculated by analyzing the construction site must be noted; variation and specifications given value is reasonable.
