Abstract

Sg. Perak Reservoir Bridge where it is commonly known to be heavily utilized by heavy vehicles on daily basis. Therefore, the practices of inspection and maintenance of this bridge are essential tasks in prolonging its lifespan especially as it is utilized heavily with heavy vehicles. The act of inspecting damage that occurred at a pier is done through the use of technical equipment as an additional method invalidating visual inspection obtained through vibration reading, and validating in inspection reading analysis as additional information to confirm for any structural damages. The use of using Global Navigation Satellite System (GNSS) can be employed for continuous monitoring and the use of accelerometers, which are components of the ambient vibration method, served to be an integral part of the information obtained on the changes in the dynamic structural features detected. The vibration measurement can display natural frequencies that depended on the weight, material, pressure, and tension as well as the geometry of the object. This data obtained can therefore be used to furnish additional information on the capacity and condition of the structure. The results indicated that maximum vibration on two piers inspection are recorded at 53.7 mm/s2 and 49.6 mm/s2 using an Accelerometer indeed heavy vehicles traffic flow is a factor in influencing bridge vibration by traffic transport diversity between west and east lanes of both sides of the bridge.
