Xi'an 710043China AbstractFinite element models of continuous rigid frame system and continuous beam system with the same beam structure are established in this paper to conduct a comparative study on the dominant influencing factors involved in the construction monitoring of rigid frame system and continuous beam system bridgesand the influences of design parameterstensioning stage and closure procedure on the cumulative displacement of girder. The cumulative displacement of girder and the cumulative displacement difference of both sides of the final closures are set as control standards to classify the linear monitoring difficulty and the various involved influencing factors are comprehensively analyzed and evaluated. The results indicate that the pre-stressing effect and the closure process have little influence on the continuous rigid frame bridge compared to the continuous girder bridge. The results of the analysis show that the structural system formed according to different prestress tension process has bigger influence on the cumulative displacement of continuous girder bridge. The influencing factors are further analyzed for reaching an appropriate closure procedure.
