A STUDY OF LATERAL DRIFT CONTROL BY CONNECTING SKY BRIDGE BETWEEN TWO BUILDINGS

Abstract

Nowadays Sky bridges are becoming very popular due to their aesthetics and the needs they serve like recreational facilities, a walkway, an evacuation option in the hour of disaster, etc. For structural purposes, controlling drift in a high rise structure is necessary. With the advent of sky bridges, engineers are looking forward to this option of controlling lateral response of the structures. To cater that need the study of controlling drift and displacement by providing sky bridge between two high rise buildings is performed here. Two high rise buildings 15m apart are analyzed without sky bridge first to find the maximum responses of the buildings such as drift and displacements. After that the buildings are connected by two sky bridges at 12th and 20th story level and the resulting structure is analyzed again. Two types of analysis are done, earthquake and wind analysis. For earthquake, static and dynamic (response spectrum) analysis and for wind only static analysis is performed. The software used for this study is ETABS 2015 which is a specific purpose software, analyzing and designing only buildings. The results obtained are then compared and conclusions are drawn later on.
