| Abstract: | This paper discusses the construction characteristics of reinforced concrete arch bridge with stiff skeleton of concrete filled steel tubes. With the use of load incremental method and with the considerations of the effects of geometrical and material non linearity and the loading process of construction, three computation models are built to analyze the stability of every construction stage of a long span concrete arch bridge with stiff reinforcement. The scopes of application of the various computation models are also presented. |
