Abstract: Sky bridges have gained popularity in recent years due to their aesthetic appeal and the recreational facilities they provide. They also serve several structural purposes, such as controlling displacement and drift. Typically, steel trusses or composite materials are used to construct sky bridges. However, this paper proposes an innovative approach using reinforced concrete (RCC) material for constructing sky bridges. The use of RCC for constructing sky bridges has several advantages, including increased durability and reduced maintenance requirements. Although the sky bridges are rigidly connected with End moments released on both sides which provide improved damping in buildings. The study utilizes ETABS19 software to model and analyse the building. This paper focused primarily on the earthquake forces that act on buildings. In this research, two buildings of similar heights i.e., 20, 24 and 28 stories are connected with one, two, or three sky bridges at different floor levels. The objective is to determine the most effective location and number of sky bridges to achieve optimal solutions. The study aims to compare the structural parameters of RCC sky bridges such as storey displacement, storey drift and base shear. This research provides valuable insights into the use of RCC material for constructing sky bridges and can serve as a basis for future studies on the topic.
