Residential Developments
The designed residential complex consists of three buildings with a height of B + GF + 8F (“tower” type) and three buildings with a height of B + GF + 8F (“blade” type). The complex is located on a plot of land with an area of about 13,939 sqm, and the footprint of the future infrastructure is about 9,770 sqm.
The infrastructure is common for the 6 buildings from a functional point of view but from a structural point of view it is divided into 9 bodies by means of joints. The structure of the basement and the foundation system make up the infrastructure.
The project was carried out in three phases:
– Phase 1: Construction of the infrastructure and superstructure for tower block (T1), the blade block (L1) and the basement area that does not have a superstructure (S1) from Intrarea Eufrosina Popescu Street;
– Phase 2: Construction of the infrastructure and superstructure for tower block (T2), the blade block (L2) and the basement area that does not have a superstructure (S2) in the central area;
– Phase 3: Construction of the infrastructure and superstructure for tower block (T3), the blade block (L3) and the non-superstructure basement area (S3).

Superstructure of "tower" type blocks
The above-ground resistance structure is a type of structure with reinforced concrete walls (structural system in which vertical, coupled or independent walls take over most vertical and horizontal loads, their contribution to taking over the shear force at the base of the building exceeding 65% of the basic shear force). The structure has a central core, in the area of the staircase. Some of the partition walls of the house and the perimeter walls are made of reinforced concrete, to ensure structure with the necessary rigidity during the seismic action as well as to balance in terms of dynamic behavior the resistance structure. The walls are 30 cm thick and they develop in two main directions. The plan sections of the walls are lamellar or with soles.
In plan sections and walls position were chosen to respect the received architectural theme, and the behavior of the structure to seismic actions is good (the structure has translations on the first two modes of vibration and torsion on the third mode; lateral displacements are below the maximum allowable limit). The structure has reinforced concrete beams arranged both longitudinally and transversely. They rest on reinforced concrete walls. The beams have a size of 30×50 cm.
Superstructure of "blade" type blocks
The above-ground resistance structure is made with reinforced concrete walls (structural system in which vertical, coupled or independent walls take over most vertical and horizontal loads, their contribution to taking over the shear force at the base of the building exceeding 65% of the basic shear force). The structure has several insulated walls in each direction. The walls in the longitudinal direction of the house are located in the area of the central longitudinal axis of the building and in the area of the core walls that house the elevator houses, and in the transverse direction the walls are distributed along the length of the building and pediments. The walls are 30 cm thick, except for some of their bulbs, which under construction conditions are 50 cm thick. The plan of the vertical elements are lamellar or with soles.
The plan sections and the position of the walls and pillars were chosen so as to respect the architectural theme, and the behavior of the structure to seismic actions is good (the structure has translations on the first two modes of vibration and torsion on mode three; the lateral movements are below the maximum limit admissible). The structure has reinforced concrete beams arranged both longitudinally and transversely, which support the vertical elements of the structure. The transverse beams in the areas of the adjacent axes to the core walls, with a large opening, will have a section of 30×55 cm, and the rest of the beams will have a section of 30×50 cm.
The infrastructure consists of the entire foundation system as well as the underground level for parking. From a structural point of view, it is divided into several bodies by means of joints.
The basement’s resistance structure is made by continuing under the considered embedded quota of the main elements of the superstructure, respectively of the reinforced concrete walls. In addition to the superstructure elements, additional vertical elements (walls and pillars) appear in the infrastructure that are arranged in the basement area without correspondence in the superstructure, in order to increase the general rigidity of the infrastructure (which must remain in the elastic behavior at seismic action).
