Structure Design and Analysis of Long-span Semi-rigid Platform Canopy

This canopy without column on the platform in the Changchun Railway Station was taken as the project example,and the structure type selection,the overall calculation and the nonlinear analysis of the long-span semi-rigid platform canopy were introduced here.Then the author pointed out that the reasonable intersection angle between the backstay cable and the canopy column as well as the initial force of the cable should be regarded as the key points in the design of this kind of semi-rigid canopy.After using SAP2000 finite element software carrying out numerical comparison and analysis,both the scope of reasonable intersection angle and the initial force of the cable have been acquired.
