Project description<br />
The project consists in the creation of a manufacture for a company<br />
producing fruit jam in an industrial zoning. It is composed of a<br />
2340 m² industrial hall for production and offices on 670 m² and<br />
2 levels. The hall has a length of 58 m and a width of 40 m with<br />
a height under ceiling of 6 m and 9 m.The offices annexed to the<br />
hall are 6,3 m tall on a surface of 11,7 m x 30,5 m including 2 levels.<br />
The entire building (hall and offices) has a steel structure for a total<br />
weight of 163T.<br />
The steel structure consists in an external framework in which walls<br />
and ceilings, made of isolating panels, are included. The hall is<br />
closed in his upper part by steel sidings and flexible metal roofing.<br />
The roof has to support external loads like snow or wind but also a<br />
walkable ceiling hanged to its structure and charged with electromechanical<br />
equipment. As a consequence, the loads to take into<br />
account are higher than for usual roofs.<br />
History of the project<br />
Initially, the client didn’t want any column inside the hall. So, we<br />
first calculated a hall relying on six rigid frames with span of 40 m<br />
spaced of 1 m with quite heavy roof loads. We made a first study<br />
with 40 m long trussed beams.<br />
We completed the calculations on this basis. After invitation to<br />
tender to the contractors, the client considered that the budget<br />
was too expensive and requested the architect company in charge<br />
of the project to tighten the budget. To reach this goal, the client<br />
agreed to implement columns in the hall, dividing the 40 m long<br />
span into two spans of 20 m. Consequently, we restarted our<br />
calculations on this assumption. Keeping trussed beams wasn’t<br />
justified anymore and we thus passed to HEA sections with bulges<br />
close to the supports. The new calculations allowed us to make an<br />
economy of 40T of steel.<br />
At the time of the new orientation taken by the project, the modelling<br />
of the structure enabled us to easily recover a good part of the<br />
work already carried out without having to start all again.<br />
Structural concept<br />
Concerning the infrastructure, because of the weak soil quality,<br />
the building is based on eighty-five 17m long piles. There is no<br />
cellar and the floors are made of a cast in place floating slab. The<br />
columns of the steel structure are fixed in the foundation pads and<br />
the façades lie on the foundation beams.<br />
Concerning the hall, six rigid frames spaced of 11 m compose the<br />
principal structure. Two of these frames have a height of 7,3 m,<br />
one makes the transition between the low and high part of the hall<br />
and the three lasts are 11,3 m tall. The four inside frames have two<br />
spans of 20 m each while the lateral ones have regular columns<br />
spaced of 5 m each.<br />
These principal frames are linked by 11 m-long roof bearers<br />
supporting the flexible metal roofing and at which hang the ceiling<br />
and the electromechanical equipments.<br />
The offices have masonry façades that aren’t bearing but just filling<br />
the steel structure. The floors are made of prestressed hollow slab.<br />
Modelling and structural calculation<br />
A complete 3D model of the steel structure was made with<br />
SCIA•ESA PT:<br />
• 395 nodes<br />
• 376 bars<br />
• 46 nodal supports<br />
• 8 load cases<br />
The actions on the steel structure due to floors, ceilings, wind… were<br />
calculated by hand and implemented in the model. The module<br />
steel code check was used to optimize the dimensioning of the<br />
structure. The connections were also checked with SCIA•ESA PT.<br />
The foundations were hand calculated using the forces given by<br />
the software.<br />
The entire steel structure was built in 10 days.<br />
Industrial hall Bakbel<br />
The project consists in the creation of a steel construction<br />
for a company producing fruit jam in an industrial zoning. It<br />
is composed of a 2340 m² industrial hall for production and<br />
offices on 670 m² and 2 levels. The entire building (hall and<br />
offices) has a steel structure for a total weight of 163T.<br />
The steel structure consists of an external framework in<br />
which walls and ceilings, made of isolating panels, are<br />
included. The hall is closed in his upper part by steel sidings<br />
and flexible metal roofing.<br />
The roof has to support external loads like snow or wind<br />
but also a walkable ceiling hanging to its structure and that<br />
is charged with electromechanical equipment. As a consequence,<br />
the loads to take into account are higher than for<br />
usual roofs.<br />
