摘要

This paper therefore investigates the reliability index of the columns of the LRT under a Level 1rn(El Centro) earthquake andLevel 2 (Tohoku-Kanto) earthquake using ordinary Monte CarlornSimulation. Based from the maiden structural plans of LRT, the slenderness ratio of columnsrnbased from the ACI 318 was observed and checked for buckling failure.The reliability indices ofrnthe light railway transit, specifically in one of its reinforced concrete pier, is 3.06 (unconfined,rnNSCP 2010) and 3.67 (confined, NSCP 2001) when it was simulated under a Tohoku-KantornEarthquake. A similar scenario was also computed for the simulation of El Centro Earthquake,rnthat is, 3.50 (unconfined, NSCP 2010) and 4.10 (confined, NSCP 2010). This can be attributedrnto the effectiveness of the confinement model used in this simulation, that is, a maximum of 92%rnimprovement of confinement in the reinforced concrete pier.
