N2 - The dynamic test of an elevated freeway bridge in Surabaya has been conducted. Eccentric mass shaker succeeded to apply an excitement to the bridge and hence the dynamic parameters such as the mode shape, the natural frequency and the damping ratio were obtained. The two main mode shapes from the test were the first vertical mode and the first longitudinal mode. The average damping ratio attained is within the range of damping ratio of prestresses concrete where the average is 2.12% whereas the range is between 2-3%. The test results are closely represented by a 3D FE model using SAP2000 without modelling the whole foundation. The deviation of the natural frequency compared to the test results is 8.50%. The elastomeric bearing effectively reduces the acceleration from upper to the bottom structure by 54.62% and 60.22% obtained from two measurements.
