Abstract
Nowadays, high-rise buildings begin to be integrated between one building with another building by making a connection between buildings, one of which is by adding a sky-bridge. In modeling a sky-bridge, several possible variations can occur, such as diaphragm characteristics and support variations. Moreover, inconsistencies often occur between the field and design. In this study, those effects on buildings’ behaviors will be investigated. The buildings analyzed were two 12-story reinforced concrete buildings that were connected to a 3-story semi cantilever steel bridge with cantilever spans of 6 m. The study results show that differences in sky-bridge modeling have huge impacts on structural behaviors and safety. If the sky-bridge makes its own diaphragm separate from the existing structure, torque becomes dominant and the buildings will need to be strengthened. Moreover, different support conditions can lead to failure in members.
