Performance-based Interaction Analysis of Damage on Bridge Expansion Joints and Heavy Traffic

An expansion joint in a poor condition typically will not be able to resist corrosion and prevent water or chemicals from penetrating into bridge bearings and piers, which will greatly expedite the deterioration process of the bridge structure. In addition to threatening the integrity of bridge structures, a damaged expansion joint may also cause serious risks of traffic accidents when vehicles pass in high speeds. According to the Federal Highway Administration (FHWA), over 60% of the joints were leaking water and 40% were experiencing problems that would shorten their service lives. According to the existing studies, the actual damage scenarios of expansion joints for a particular bridge can be pretty complicated. One critical challenge lies on the failure of rationally considering the interactions of bridge joints and vehicles, especially considering the deteriorating process of the joints. For example, traffic loads induce more dynamic impacts on the joints which cause damages. More damages, such as unevenness will cause more dynamic interactions with passing vehicles, which in turn cause more impacts loads on the joints from the vehicles. Such a process continues which will accelerate the deterioration process of the joints. As an important step toward tackling the accelerating damage problem of expansion joints, the objective of this study would be to characterize the basic interactions between the passing traffic and the deteriorating joints by developing a rational model. As a result, better understanding of the lifetime performance of the joints can be achieved.
