预应力混凝土连续箱梁钢束效应分析及调束

Analysis and Adjustment of Steel Tendon Effect in Prestressed Concrete Continuous Box Girder

结合具体工程实例,利用有限元分析软件,对(42+70+42)m预应力混凝土连续箱梁进行建模计算,通过分析腹板束、顶板束及底板束的主效应、次效应的分布特点,优化钢束配置,为该类桥梁配束提供参考。

Based on specific engineering examples,finite element analysis software was used to model and calculate the(42+70+42)m prestressed concrete continuous box girder.By analyzing the distribution characteristics of the main and secondary effects of the web beam,top plate beam,and bottom plate beam,the steel beam configuration was optimized,providing reference for the reinforcement of this type of bridge beam.
