STUDI KASUS KERUSAKAN JEMBATAN DAN PENGARUHNYA TERHADAP SISA UMUR JEMBATAN

Abstract

This paper presents the results of research case studies of bridge damage and influence on the remaining life of the bridge. This research takes the case of the highway bridge between kebon jeruk – penjaringan west of jakarta. The purpose of this activity is to get an idea of the residual life of the bridge that is related to the presence of defects in the structure of the bridge. To determine the actual condition of the bridge, performed data collection by measuring the compressive strength of concrete, crack depth, crack width, thick concrete cover, reinforcement diameter, reinforcement spacing, deflection due to load and run. From these data made feasibility and serviceability analysis to determine the value of the bridge.condition. Furthermore value condition used to predict the residual life of the bridge. The results of the residual life analysis showed that highway bridge on 1 segment , who suffered damage to the value of the condition 2.67, residual life if the damage continue only 1.07 years, and if the damage does not continue, the remaining life of 11.67 years. For segment 3 which suffered minor damage with the value of condition 2, residual life if the damage continues only 2,125 years, and if the damage does not continue the residual life of 18.89 years. Keywords: bridge, pile slab, value condition, feasibility, serviceability, remaining life.
