Simulation of Failure Mechanism of RC Column Before and After Seismic Strengthening

Fumiaki UEHAN, Kimiro MEGURO


  For earthquake disaster measures of railway systems in the future, it is indispensable to detect weak points of RC structures correctly and provide effective and economical reinforcement. In this paper, we study the applicability of Applied Element Method as an evaluation tool for the seismic performance of RC structure with and without applying seismic strengthening technique. The termination of main reinforcements is taken up as a weak point of RC column. The change in the failure mode of RC columns due to the change in the anchorage length of main reinforcements is simulated. Moreover, simulations are also carried out on the effect of the seismic strengthening of the RC columns with steel jacket.
