预应力混凝土交叉转换梁的结构设计及实测对比

摘要

Girder transfer floor structure has been used in housing building and bridge engineering which can solve the problem of vertical interruption of a whole structure. However, the practice case of supporting a column with cross transfer girder is quite few. Associated with in-site test of a railway station viaduct crossed transfer girder, the design method of prestressed concrete crossed transfer girder was studied as well as the characteristics of transfer girder was explored in this paper.%梁式转换层结构可以用在房屋建筑中也可以用在桥梁工程中，其作用都是解决结构在竖向的不连续的问题。在桥梁工程中，采用交叉转换梁实现托柱的国内外工程实践均不多见。本文结合某火车站站前广场高架平台桥工程的现场监测，进行了预应力混凝土交叉转换梁设计方法的探讨，初步揭示了带转换梁结构和转换梁自身的受力特点。
