Behavior Analysis of Forensic Audit Results at Pier 3 Mahakam Bridge
Keywords:Concrete, Forensic, NDT
The Mahakam Bridge that connects Samarinda Kota and Samarinda Seberang was again hit by a coal pontoon, the force of the impact caused the bridge body to vibrate. The collision caused the bottom of Main Pillar 3 (P3) on the Samarinda Kota and Samarinda Seberang sides to crack, as well as two defective foundation pile pipes. Non-destructive Test or non-destructive test is a Material Testing Technique without Destructing the Test Object. This test is carried out to ensure that the material we use is still safe and has not exceeded the damage tolerance limit. Based on the results of data analysis that has been carried out, it can be concluded that the results of the hammer test plate test on the Mahakam Bridge for the entire side of Balikpapan obtained a surface density value with a compressive strength of 296.3 kg/cm2, the results of the hammer test plate test on the Mahakam Bridge for the entire Samarinda side obtained the value of the surface density with a compressive strength of 452.8 kg/cm2 while the results of the UPV examination can be seen that the value of the density of the concrete quality on the pier is 20.4 MPa. From these results it can be concluded that the concrete quality criteria are not good enough - good enough. There is a match between the behavior of the damage caused by the collision of the head between the results of the visual inspection and the results of the behavior using FEM.
