Abstract

Interaction between the foundations and the ground of the structure can trigger a major effect on the building. In general, stiffer foundations resulted in higher natural frequencies of the building-soil system and higher input frequencies are often associated with other ground. Usually, vibrations transmitted to the buildings by ground borne are often noticeable. This is because the ground borne vibration can be felt and it might affect the building worse if the vibration level is high. UTHM campus area is prone to the ground borne vibration due to the traffic from the main road, and the constructions of several additional buildings. Therefore, the effect of vibrations produced by the movement of the traffic is higher than the other sources. This paper investigates to determine the natural frequency and vibration mode of multi storey office building due to the presence of foundation system and without foundation system and also comparison between both systems. Finite element modelling (FEM) package software such as LUSAS is used to perform the vibration analysis of the building. The building is remodelled based on the original plan with the additional of the foundation system on the structure model. Final results indicated that the structure without foundation system have high natural frequency rather than the structure with foundation system due to soil structure interaction and also the damping of the system which related to the amount of energy dissipated through the foundation soil.
