A Review of Ambient Vibration Technique on Bridges

Abstract

Abstracts. Bridge is one of the important facilities use in daily life as a bridge is built to span physical obstacles such as a body of water, valley or road for the purpose of providing passage over the obstacle. Various testing conducted on the bridge in order to know the dynamic characteristics of the bridges. One of populartesting use isan ambient vibration test. Ambient vibration is a nondestructive test conducted using highly sensitive sensor. This testing iseasy to conduct with less labour, time and also cost. This paper aim to provide up to date literature review on ambient vibration test on bridge includes sources of ambient vibration, procedure of conducting the measurement and results from the ambient vibration test.It is important to known the dynamic characteristics of the bridge especially to determine the dynamic response of the structure and also as dynamic information for seismic design.
