Abstract:
A structural deterioration of infrastructure system is inevitable. As
the deterioration process affects the performance of the infrastructure system,
structural assessment and strengthening technique are needed to resolve the
issues. Cikeusik multispan steel bridge that was built in 1970's is part of
Cikeusik Weir which connected with eight pillars of reinforced concrete.
Assessment results which accomodate by conducting destructive, nondestructive
test as well as structure modelling tools show that those pillars are
in near severe condition. In order to restore the pillars performance, retrofitting
are necessary to be implemented. However, selection of a structural retrofitting
alternative is not an easy task. Steel jacketing, concrete jacketing and fiber
reinforced polymer are among those available alternatives. Through semi
quantitative method of decision making, the concrete jacketing is the most
suitable alternative for strengthening the pillars.
