Abstract
Reliability and durability of railway bridges have regularly to be monitored. Factors such as construction defects, structural deterioration, material degradation and aging, harsh environmental conditions, changing and increasing loading, as well as extreme events such as natural disasters may contribute to the failure of an infrastructure system to various degrees. Railway bridge structural health monitoring technique is necessary rather than visual inspection alone and it may not be adequate. This study presents a critical review of indirect methods for railway bridge monitoring system. Before installing instrumentations on the bridge, a numerical simulation was performed to have overview of the critical location on the bridge due to actions on existing bridge. This paper provides discussion and recommendations on the challenges to be overcome for successful implementation in practice. This case study may be of useful to practical engineers and researchers.
