Use of non-destructive methods: Case studies of marine port and bridges structures in Surabaya

Abstract

Consideration of degradation due to harsh environments, overweight vehicles, increasing traffic and frequent earthquake events are some of the challenges to overcome when designing reinforced concrete bridges. Structural elements can be affected by a reduction in strength and stiffness due to the carbonation of the concrete cover, the corrosion of the reinforcement, excessive cracking and displacement under service load and failure. Therefore, structures need to be monitored over time to ensure that they have the sufficient capacity to resist the intended design loads. The existing condition of bridges on toll roads and in ports located in Surabaya Indonesia has been investigated using non-d..
