| Abstract: | For the steel cable-stayed bridge of second Nanjing Yangtse River Bridge,a 3-dimensional compound structural calculation model constructed by beams and rope elements was used to analyze the structural behavior of the bridge.In the analysis,the structural nonlinearity and ultimate bearing capacity of members were considered,and the deformations during construction and the superposition effect of stresses were also taken into account.The emphasis of the study was focused on the structural stability during construction. |
