Continuous condition monitoring of bridge structures in India becomes essential because many of the bridges were constructed long ago with loading conditions as per old codal provisions. The bridges have become weak and distressed due to the increasing vehicular traffic which in turn reduces the performance and safety of the bridge. Also the information about the old bridges such as capacity information is not available. The problem is more pronounced in rural areas compared to urban places where visual inspection is frequent and necessary infrastructure is available for immediate revival. Vibration based condition monitoring detects structural integrity and conveys a warning message if the integrity is defective. This paper presents the condition monitoring of RCC slab bridge deck which is designed for rural areas, by conducting test on small scale model. The test specimen is a 1/4th scale deck slab of 1500 mm long, 1100 mm wide and 110 mm thick. The experimental and analytical results are presented in terms of frequency, deflection, crack width and stiffness. © IAEME Publication.
