| 摘 要： | 镇海仓库采用大跨预应力混凝土框架结构.主要对三层两跨预应力混凝土框架进行了考虑张拉施工方案的计算分析.结果表明,现行设计法所得的预应力综合弯矩和预应力次弯矩与实际值有较大的偏离.为保证按逐层法施工时现行设计法能满足框架控制截面的抗裂和承载能力要求,提出了修正方法.

| Abstract: | Construction process of multi-story prestressed concrete frames(MPCF)should be noted in structural analysis because the sequence of steel tension and concrete pouring directly affects building mechanical model.But in general it is not considered during designing MPCF.The calculated model of the main platform in the Zhenghai Storehouse is analyzed with the construction process taken into account.The key site is reinforced in order to satisfy the requirement of cracking capacity and bearing capacity of prestressed frame. |

| Keywords: | prestressed concrete frame construction scheme |
