Elastomeric bearing is a significant device in structures such as in bridges and buildings. It is a combination of rubber and steel shim plates in alternate layers that provides a very high vertical stiffness, while still maintaining high flexibility in horizontal direction which is required to lengthen the time period of a structure during the sei...

... the FRF, the dynamic properties which are the natural frequencies, mode shapes, and damping of elastomeric bearing were determined using the PULSE Reflex software. Figure 5 shows the full diagram of the experimental analysis. Figure 6 shows the frequency response functions (FRF) of the elastomeric bearing from the experimental modal analysis. ...

This study presents results of an experimental investigations of the materials used in passive damping vibrations. The main purpose of this paper was to examine the damping properties of selected viscoelastic materials (VEM), using the modal analysis. In presented analysis three configurations of specimens were considered. At first, the separated s...

... There are basically integrated techniques involved in modal analysis not only to identify but also to predict the dynamic properties of a structure: finite element model, modal testing, and finite element model updating. The integrated technique has been verified in many research papers in testing of multi-storey building, grandstand, tower and bridges [19]- [23] [24]- [26]. The advantage of the application of finite element analysis is to help the experimentalist to modify the structure in order to correct any raise of problem. ...

Nowadays, the pedestrian bridge is design and build to increase the safety awareness for the public to crossing roadways without disturbing the vehicular traffic. However, the failure of a pedestrian bridge for the recent year such as at the Florida International University tragedy make people think twice to use the footbridge because of their doubtful. Therefore, this study is to convince the people that the existing pedestrian bridges are safe to be used by investigated their dynamic performance. To achieve this objective, finite element model of an existing steel pedestrian bridge was developed using commercial software through the modal analysis application. The Dynamic Behaviour of Existing Steel Pedestrian Bridge http://www.iaeme.com/IJCIET/index.asp 1444 editor@iaeme.com developed finite element model was validated by having identical dynamic properties with those determined from theory and it also lies in the safe range of design standard code. Hence, this study provided the authority management to have their infrastructure database which can be used in their structural monitoring and maintenance work before any intervention is undertaken.
