| Abstract: | The paper take a Concrete-Filled Steel Tubular X-arch bridge with a span of 112-meters as an example and established a 3D computational model by adopting the large-scale finite element analysis software-midas civil,meanwhile made a simulation of the construction process.The paper also analyzed the stress and the distortion of the structure in the construction process and provides some reference for the control of the structural construction.The alignment of built bridge is in accord with the expectations,an... |
