Parking Building
Urbanização Sul
2002
PECS was responsible for the structural and foundation projects and for some specialties of the parking building located in Benfica, Lisbon.
In addition to the development of the projects, he was also responsible for their coordination and for monitoring the respective administrative licenses.
The building has five underground floors and a ground floor with coverage in specific areas. The excavation to be carried out has an area in plan of approximately 3440 m2 and an average height of about 14.00 m, making a total volume of approximately 48 850 m3.
Description
The structure designed for the park is entirely in reinforced concrete and consists of a solid fungiform slab, with running spans of 7.40m in both directions, with a current thickness of 0.25m. In some areas the spans reach 8.40m in both directions, in which case 3.0´3.0m2 capitals were used on the pillars, with 0.35m of total thickness, to reduce deformations and increase the resistance to bending and punching. The pillars, currently aligned on axes, have current sections that vary between 0.30´1.00 and 0.30´1.40. The walls of the stairs and elevators are in reinforced concrete and form an integrated core.
The building is bordered by earth support walls, since it is practically all buried. These are made of reinforced concrete, with a current thickness of 0.30m and are built from top to bottom, according to the construction process of “Munich” type walls. In the final phase, they will be blocked by the floor slabs, rigid in their plane, which will thus constitute supports, so that the walls work with continuity between sections and with main flexion in the vertical direction.
