Abstract

Subway is an underground tube which is used to carry underground roadway and railway systems within urban and suburban areas. To reduce the traffic volume above the ground underground Subway is used to connects many busy places through a common route. Many Metropolitan Cities in India are on the verge of getting saturated due to Urbanization therefore the Planning and Construction of such underground Subway is very much important in the modern times. The main aim of the present study is to reduce the traffic volume above the ground and study the structural behaviour of boxed shaped Subway under various loading conditions for the road way system. The structural loads are considered as per Indian Road Congress (IRC). Modeling of subway is carried out by using four node plate element using a computer program i.e. STAAD.Pro. The structural behavior of subway is observed for principal stresses, for a load combination as per IRC. Prestressing is design for maximum tensile principle stresses in a structure as a system to enhance the performance.
