Abstract
The present work investigates the effects of structural links on the modal properties and seismic-induced responses of a linked building system (LBS) The LBS in this work refers to a system consisting of twin buildings horizontally connected by structural links such as sky bridges or sky gardens. The analytical model for the LBS is formed by assembling the rigid diaphragm model of the building. The LBS in this work refers to a system consisting of twin buildings horizontally connected by structural links such as sky bridges or sky gardens. The analytical model for the LBS is formed by assembling the rigid diaphragm model of the building Results showed that the connections of the linking bridge have a significant effect on the overall dynamic response of the bridge in both longitudinal and transverse directions. In order to achieve the goal, the modelling and analysis of the building towers and the sky bridge was accomplished using SAP2000 software. The maximum horizontal deflection of the building towers at the topmost level under serviceability limit state as well as storey drifts of building towers was compared to determine the effectiveness of the sky bridge in terms of location and number of links.
