摘要
在转换结构中,转换层充当了上部结构"基础"的角色。针对转换梁变形控制的重要性,从工程设计的角度提出了一种对部分预应力混凝土转换梁进行变形控制的近似分析方法,该方法在结构整体计算中的实现为在实际工程中的运用提供了可能。同时,对施加预应力控制转换梁变形的效果进行了分析。鉴于目前国内文献中缺乏这方面的资料,文中提出的计算方法和分析结论可供相关的设计人员参考借鉴。
In transfer structures,the transfer story serves as a ＂foundation＂ of the upper structure.So the deformation control of the transfer beam is a key problem in the structural design practice.A proximate analysis method was presented in this paper,the realization of the method in the global structural calculation make the use of the method possible in practical engineering projects.Meanwhile,the effect of controlling deformation of transfer beams by applying prestress was analysed,which may give some references to the similar project.
