| 摘 要： | 针对预应力混凝土箱梁体内外混合配束方式,应用大型有限元软件ANSYS,对某简支箱梁模型的线弹性工作阶段进行受力分析,并将计算值与试验值进行比较,结果表明,ANSYS分析方法能够较好地模拟实际受力情况。借此建模方法通过相关参数分析,考虑预应力筋数目、力筋布置位置和张拉预应力等因素对箱梁受力性能的影响,为今后的体内外混合配束预应力箱梁设计提供一定参考。

| Abstract: | Aiming at analyzing the mixed arrangement of internal prestressing and external prestressing of prestressed concrete box girder,analyzed the linear elastic session of the model of simple-supported box girder by using large finite element software ANSYS,and compared the calculated with trial value.The results show that the method of ANSYS can effectively imitate realistic mechanical properties.By using this modeling method,related parameters and considering the influence of mechanical properties to box girde... |
