摘要
施工期间的预应力混凝土结构是时变体系。通过预应力等效荷载分析和梁板柱混凝土结构的施工阶段受力分析,计算作用于预应力混凝土结构上的荷载。将留后浇带预应力混凝土梁模拟为弹性支座梁,研究了留后浇带预应力混凝土结构施工期间的力学性能。结果表明,预应力等效荷载和施工荷载直接影响预应力混凝土结构的施工安全。
The prestressed reinforced concrete structure during construction is a time-dependent structural system.The loads acting on it include construction load and prestressed equivalent loads.Based on the theory of prestressed concrete and time-dependent structures of beam-slab-column concrete structures during construction,the loads are studied.The structures are simulated as a beam with elastic bearing, then a model is proposed for the analysis of prestressed concrete structures with a strip of post pouring concrete during construction.Study shows that construction load and prestressed equivalent loads have obvious effect on its safety during construction.
