Abstract
In the last period, high rise buildings were considered from the very important and special structures.Today,in modern cities and due to limited available land tall buildings are often constructed close together.To connect adjacent tall buildings; sky-bridges are frequently used. This research investigates the effect of wind and thermal loads on two adjacent, tall buildings that are connected by a sky-bridge.The investigation addresses the straining actions in the main beams of the sky-bridge as well as the base shear and overturning moments that act on the two buildings. A comparison between results is carried out considering few controlling parameters (bridge span, bridge elevation,bridge boundary conditions, and geometry of the two buildings).It is attempted to determine the ideal boundary conditions for sky-bridges that reduce forces in bridge structural elements as well as in the two connected buildings.It was found that the effect of the elevation of the bridge on the axial forces induced in its main beams due to wind load in x-direction (direction parallel to the bridge) is bigger than the effect of its span whose effect is relatively small. The opposite appears in cases of wind load in y-direction (perpendicular on the bridge) and thermal loads,as the bridge{u2019}s elevations and spans both have a significant impact on the axial forces induced in its main beams due to these loads
