摘要
结合工程实际,应用有限元软件MIDAS FEA建立空间实体模型,对支撑比大于4的大挑臂多腹板箱梁偏载作用下的腹板不均匀受力效应进行分析,比较不同支座间距下腹板偏载系数分布特点,探讨合理的偏载系数的取值,并作了适当的总结和归纳。
Baesd on practical engineering,solid model were established respectively by finite element software MIDAS FEA in order to carry on the analysis on the non-uniform force of Multi-web box-girder with the support ratio greater than four Distribution characteristics of Eccentric load coefficient with different support spacing and the reasonable value of Eccentric load coefficient were discusses and summarizes.
