With urbanisation and increasing popularity of automobiles, parking structures have become a necessity throughout the world. Over 3000-4000 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. celysis.

If the land is cheap and plentiful in the area where parking is needed, then surface parking is provided. However, if the land is scarce and expensive, as is the case in most towns and cities, then a multi-story parking structure will likely solve the parking issues. Parking needs differ from one type of development to the next and therefore virtually each parking structure needs to be designed for the type, number and nature of the visits it will serve. However, providing a parking structure is an expensive proposition.
