摘要
基于16根两跨无粘结预应力混凝土连续梁试验结果,考察分析了试验梁塑性内力重分布性能,建立了以中支座相对塑性转角为自变量的弯矩调幅系数计算公式,为无粘结预应力混凝土连续梁按塑性方法设计及相关标准的修订提供了试验依据。
Based on experimental results of sixteen two- span continuous concrete beams prestressed with unbonded tendons, the formula of coefficient of moment modulation in critical section of mid support are proposed, in which relative ultimate plastic rotation is the basic parameter. All these may be served as testing basis of plastic design of continuous concrete beam prestressed with unbonded tendons and emendation of relative standard.
