摘要
在修正钢管混凝土弹性模量的基础上 ,将钢管混凝土桁式拱桥拱肋等代成闭合箱来计算拱肋内力和位移 ,在不失结果准确性的前提下 。
On the base of modified axial elastic modal for CFST, the CFST truss arch rib was equaled a closed box arch in order to calculate the internal forces and displacements of arch rib, on condition of outcome veracity, its workload reduced comparing with other calculating modes.
