Design and Construction of Parking Structures
With urbanization and popularity of the automobile, parking structures have become a necessity throughout the world. Over 2000-3000 new automobiles are being added per week on the roads for cities such as Mumbai and Delhi. Parking structures have many attributes in common with buildings but also have unique differences. A unique aspect of a parking structure is that, in most cases, it must have a vehicular circulation system to provide access from one floor to the next, necessitating sloping ramps or helices. Further, unlike residential and commercial buildings, the parking structures are open, unheated and undergo volume changes that cause additional distress in the framing elements and affect structural ability to withstand its design loads. This paper reviews the state-of-the-art in design of precast-prestressed and post-tensioned concrete structures from structural design to durability and safety considerations.
