Assesment Of The Air Putih Slab Bengkalis District, Riau Province (Case Study: RORO Air Putih Wharf)

A pedestrian bridge is one of the important things that people need to cross from one island to another. However, there is one element called the slab on the bridge that requires special attention and its strength is important to always reviewed periodicaly because it holds the bridge from collapsing. This review can take the form of a visual review or analysis. Visual inspection can use the guidelines developed in the Bridge Management system in 1992. In BMS 1992, the review is carried out based on the final score, where each score represents the condition of the bridge, the higher the score obtained, the more dangerous the bridge is. This research carried out two stages of analysis, which included a visual inspection and an analysis of the load that the pier could withstand. This research carries out finite element analysis by modeling the slab on the bridge according to factual conditions. This modeling is carried out by analyzing one slab segment and finding out how much deflection occurs when a load is applied to the slab. Research shows that when a vehicle is loaded at 35069 N/mm2, a displacement of 0.797 mm is obtained. Meanwhile, with visual testing using dial gauge data processing, a deflection of 1.26 mm was obtained. There are differences between visual analysis and modeling analysis. This can occur because of differences in quality and field implementation when the slab was made.
