Eurocodes in Practice: Structural Design of a Residential Building Using LIRA-FEM

The designed facility is a building with an attic floor and a three-level underground parking garage. The underground part of the structure is formed by reinforced concrete pile walls. Plan dimensions are 67.0 × 40.0 m and 25.0 × 27.0 m. The height of the three underground parking levels is hₚ = 3.25 m; the height of the above-ground floors (levels 1'4) is hₐ = 4.8 m. The total height of the building above ground level is H ≈ 19.0 m. The building is divided by expansion joints at floor levels into deformation blocks; the maximum distance between joints is L = 35 m. The blocks are connected by an underground tunnel.

Structural system: monolithic reinforced concrete foundations on bored piles with pile caps. The perimeter of the underground part is formed by pile walls. Monolithic reinforced concrete plinth beams; walls of staircases and elevator shafts; columns; floor slabs (beam-and-slab systems are used in zones with high loads). Reinforced concrete elements were analyzed and designed using reinforced concrete design software integrated within the LIRA-FEM computational environment. Pitched roofs are supported by steel trusses. Slabs are rigidly connected to columns and walls. Columns are monolithic reinforced concrete. Staircase walls and elevator shafts are flexibly connected to the foundations. Steel beams are hinged to reinforced concrete structures. Bored piles are used. During foundation construction near streets and existing buildings, temporary ground support measures are provided.
