Overview

The building host facilities open to the public as part of a regeneration project on a previous industrial site, where a steel company had its production facilities for decades. The building therefore was conceived with a structural steel frame, to acknowledge the “history” of the site. The main feature of the requalification job consists in an auditorium for 300 seats, and a sport/fitness center for about 7600 square meters.

Issue and/or innovation

The architectural design of the auditorium called for a lightweight and luminous space, with the abundant penetration of natural light. This requested a steel skeleton to be designed.

Reason for composite solution

To give enough stiffness and proper acoustic performance to the floor, a heavy design solution was needed and this was achieved through the use of an heavy concrete slab.

Specific solution/technical details

The inclined composite floor of the auditorium is supported by a frame spanning 7.9meters. Each frame is composed of two coupled HAS 760/216 beams, welded together, supported by concrete columns. The secondary beams are formed by either HSA600/180 beams (aligned with the concrete columns) and IPE 500 beams with a distance of 2,66 meters one another and finally tertiary beams made with IPE 240. The corrugated sheet (A55/P 600 with 0.8mm of thickness) and the concrete above works compositely with the beams by means of shear studs and a 8mm 15x15cm welded wire mesh.

Impact or effectiveness

The construction of the composite floor proved to be an effective solution thanks to the rigidity of the slab that offers a support to both the auditorium seats and its enclosure.
