Grand Prix of 'Architektura Roku Województwa Śląskiego 2003'
A 3-floors steel-framed extension is supported by a steel grillage that is placed on a top of a roof of an existing building and is cantilevered to the line of building avant-corpses
It is the role of the grillage to transform the column reactions of the designed frame into possibly uniformly distributed loads that is acting on the existing walls
Due to a large part of the extension in relation to the old one that considerably exceeds the existing standards - any structural & material solutions was taken to achieve possibly the most slimming of extension but having regard to the necessary comfort of use also.
The design solutions in terms of individual elements of the structure are:
- cantilevered and placed on the walls continuous beams of the grillage was designed as IPE500 with exception of the compound IIPE500 that are placed on the inner walls leading ventilation ducts
- the built on the grillage 3D frame was designed as transverse frames comprise a HEB200 columns, 4-span IPE330 beams and 3-span the IPE300 roof beams; in the perpendicular direction longitudinal HEB200 beams of 6 and 6.3m length was taken
- light floor slabs on 4 levels /also in the grillage level/ consists of a reinforced of R131 mesh 6cm in-situ concrete on TR35/207/0.63 metal deck supported by IPE 200/240 joists in 1.2m spacing. The upper finish of the floor - 2.5cm and the ceiling at the bottom
A reinforced elements range in the existing masonry structure has been reduced to the minimum - mainly for the provided modernization purpose like the increasing of existing openings or execution of new ones.
