The architectural project covers two blocks and includes not only the construction of several residential and commercial buildings, but also the implementation of the streets and surrounding landscaping.
The intervention involves the construction of residential buildings root assigned to lots 1, 2 and 3 and include the construction of two cellars for private parking and seven floors above ground, including coverage for housing. The existing areas in terms of r / floor intended or installation of commercial premises or to be transferred for public enjoyment, either in walking or in access from traffic.
Each independent bodies comprises reticulated structure comprising reinforced concrete pillars and solid slabs. In addition there are the cores of reinforced concrete boxes, lifts and stairs, walls and tops that are essential to ensure adequate resistance to horizontal actions of the building wind and earthquake and to ensure that the locking required for the structure can be considered as fixed nodes in both directions. In defining the location of the joints sought to ensure the symmetry of the nuclei and "shear-walls" to minimize the effects of torsion in buildings.
The areas over traffic and pedestrian, provided at floor level, we propose a structural solution that considers maximum spans of about 12m, then considering the use of solid slabs of reinforced concrete by post-stressed system pre -effort non-adherent using mono-torons.
