摘要:
在PPC超静定结构弯矩调幅的研究中引入曲斗延性,使得结构满足承载力要求的弯矩调幅限值可以由理论计算求得. 在弯矩调幅的取值上,考虑了使用阶段裂缝宽度限值和初铰出现迟早的影响. 最后给出了PPC超静定结构弯矩调幅的计算公式.
Abstract:
In the study of ultimate moment modification of PPC hyperstatic structures, the ultimate moment modification can be calculated theoretically according to curvature ductility. At the same time, the moment modification is influenced by two factors, one is maximum crack width in service loading, the other is the time at which the first hinge takes place. At last, the formulae for calculating moment modification of PPC hyperstatic structures are offered.
