| 摘 要： | 结合河南卫河大桥工程实例,采用数值分析法中的有限元法,研究各受力参数对单箱三室波形钢腹板PC组合箱梁横向应力的影响;揭示单箱三室波形钢腹板PC组合箱梁在集中荷载和汽车活载作用下,箱梁的横向应力峰值的变化规律。计算数据表明,各室中心线正弯矩区和各腹板加腋处负弯矩区为单箱多室波形钢腹板PC组合箱梁的横向受力最不利位置。

| Abstract: | In the engineering case of Weihe Bridge in Henan,series of three-dimensional models have been generated,which adopt the finite element analysis.From the results,the influences of parameters to girder transverse stress have been studied.The transverse stress under the dead load and the vehicle load is calculated by the finite element soft too.The distribution regularity of the transverse stress is also discussed,which would be useful in the design of this kind of girder.It is indicated from the results that ... |
