大跨度预应力混凝土转换梁结构技术研究

Research of Large Span Prestressed Concrete Transfer Beam Structure

对预应力混凝土转换梁结构的施工要点作了分析,转换梁和上、下部结构有明显的共同工作特性,尤其是转换梁下部层数的多少即下部结构的刚度对转换梁的内力影响较大,对转换层的选型和设计有重要意义.

This paper analyzes the construction points for the converted beams of prestressed concrete.The transfer number of beams and the upper and lower part of the structure have obvious common operating characteristics,especially the number of lower floors of the transfer beam,namely,that is stiffness of the lower part of the structure has greater impact on the internal force of the transfer beam,which is of great significance to selection and design of the conversion layer.
