Effect of Construction Stages to Long-Term Behavior of a Long-Span Pre-Stressed Concrete Girder Bridge

Abstract:

Questions arise whether construction delay combined with construction method modification of a long-span bridge will affect bridge resistance to withstand the working load in the long term. A continuous bridge with a span of 78 m - 145 m - 77 m that crosses a large river has experienced this condition. In its implementation, there was a difference in construction time compared to the initial design. As a result, it is necessary to conduct an analysis of the effects of the difference in construction time on the bridge structure. An analysis of the stages of bridge construction was carried out using the Midas Civil program to determine the stress and deflection that occurred. Stress and deflection over a long period of time were calculated to determine the effect of construction methods and delays.
