Abstract

In many cases the only places available for the construction of a new car park are the existing streets or roads. These streets may also have important or historic buildings very close to the structure, which means that they cannot be disturbed in any way during the construction of the parking structure. In this particular case, the novelty is that the top deck is solved with a unique structure: a vault that interacts with the pile wall not only for vertical but also for horizontal loads due to the arch mechanism. The construction of the vault is solved as a large precast element of one piece of more than 16 in length and 2.40m in width, which is built in the factory, transported with the help of trucks and erected on site with large cranes.

Highlights

  • Parking structures can be built both above and under ground

  • A solution is to build a pile wall in the first place to limit the deformations on the ground and to protect the buildings around and afterwards start building the rest of the structure (5)

  • For parking structures, when the situation does not provide enough land for a new structure above ground new solutions have to be developed. This is normally the case inside the cities in Spain where there is an important need for parking places but almost no place to build them
