某变截面连续箱梁桥静力计算分析

On static force calculation and analysis of some variable cross-section continuous box girder beam bridge

采用有限元分析软件Midas/civil,建模分析了变截面预应力混凝土连续梁桥在荷载、沉降等因素影响下的弯矩、剪力包络图,并对其挠度进行了验算,为今后预应力混凝土变截面连续梁的设计、分析、研究提供了借鉴。

The paper adopts Midas/civil finite element analysis software,undertakes the modeling analysis of the bending moment and shearing envelope diagram of the variable cross-section continuous box girder beam bridge affected by the loading and settlement,and calculates its deflection,so as to provide some reference for the design,the analysis and study on the prestressed concrete variable cross-section continuous girder in future.
