Modal parameters identification of light rail bridges

open access: yesIOP Conference Series: Materials Science and Engineering, 2019
Abstract One of important aspect in Structural Health Monitoring System (SHMS) is the initial condition of the structure. This paper studies the initial condition of light rail train (LRT) bridges before officially operated. There are four bridges to be evaluated, consists of three simple supported bridges and one continuous bridge. Data
