Considering that the reinforced pipe rack participates in the overall force,the overall reinforcement pipe rack was simulated by using the finite element software,the bearing capacity of the model of monolithic plane frame and the overall calculation model using the same structural characteristics were analyzed.The results showed pipeline involved in the overall force,the overall support force value of reinforced pipe was smaller than the monolithic planar frame calculation,and the difference value of reinforced rack closer to fixed tube frame was small.In order to reduce the amount of steel,we may reduce appropriately its reinforcement steel sections.%考虑加固后的管道支架参与整体受力,采用有限元软件对加固管架进行整体模拟,对比分析采用外包钢加固管道支架单片平面框架计算模型和采用相同结构特征的整体计算模型的承载力值.分析表明:管道参与整体受力,加固后的管道支架整体受力比单片平面框架计算值较小,且靠近固定管架的加固支架差值较大,可适当减小该处加固型钢截面,以减少用钢量.
