Stress distributions of PSC box girder bridge due to creep shrinkage effect
Long-span bridges are usually designed with a service life of more than 20 years. Thus, it is required to consider factors that are affected by time. Creep and shrinkage are parameters to predict time-dependent behavior of a bridge. The purpose of this study is to determine the effects of creep & shrinkage toward total stresess. Lemah Ireng 1 Bridge in Semarang-Solo toll road was used as a case study. The bridge has a total span length of 879 m. It has a service life design of 100 years. Therefore, this creep and shrinkage research is necessary to determine the stress distribution in the box girder bridge until the end of the service life. Computational modelling was conducted to estimate the stress distribution in the structure of the box girder bridge. Several stages of loading on the bridges were applying asphalt leveling, barrier, creep and shrinkage load by using a variation of the long-term duration with intervals of 5, 10, 15, 20, 40, 60, 80 and 100 years. The analysis was using linear static method, Construction Stage Analysis-Time Dependent effects on Midas Civil and only apply non-transient load on the bridge structure. This study is expected to show the impact of the creep and shrinkage effects of the total stresses along the bridge span until the service life of 100 years.
