摘要
本文通过对一多层预应力混凝土框架结构算例进行分析,比较了按不同张拉施工方案建造的结构中预应力所产生的次内力,指出设计时应采用与实际施工方案相符的结构分析模型来计算预应力的次内力。
By analysising a multi-story PC frame structure, the secondary intemal intemal forces in the structures built using different constructing processes is compared.It is pointed out that the model of calculating secondary intemal forces should accord with the construction plan when designing a muulti-story PC frame structure.
