Introduction to the project
This project includes a new structure for an industrial
enterprise that supplies fresh seafood and packages
the produce prior to sale. The enterprise also has the
means to freeze seafood.
The new structure consists of a two-floor building
with a basement. On the first floor, the seafood will
be delivered for all the necessary processing prior to
the final packaging phase. On the first floor will sit the
offices of the enterprise, while the basement will be
used for stocking frozen products.
The location of the structure is very close to the
larger port in the area. Therefore, the seafood can be
delivered very quickly and the frozen products can be
sent on to other places or countries.
The total area the industrial enterprise will cover is
approximately 900 sqm.
Description of the project
The structure was designed from steel members and
concrete slabs. Due to the complicated architectural
view, a 3D model was designed.
Approach
We used HEB for the columns, HEA for the main
beams, IPE for the secondary beams and an SHS
cross-section for the wall bracing.
The secondary beams were designed using the
composite beam module in order to reduce the total
weight of steel.
To simulate the diaphragm of the concrete slab,
HEA1000 for roof bracing was used, without weight and
mass, using property modifiers.
The use of Scia Engineer in this project
We designed the 3D model using the Line Grid option.
The next step was to make all the load cases, load
groups and load combinations.
Load groups:
1. G : permanent
2. S : snow
3. W : wind
4. E : seismic
5. Q : variable
Load cases:
1. LC1 : self-weight
2. LC2 : permanent
3. LC3 : variable
4. LC4 : snow
5. LC5 : seismic X
6. LC6 : seismic Y
7. LC7 - LC22 : 3D Wind Load Cases
Load Combinations:
1. EN-ULS
2. EN-SLS
3. EN-seismic X
4. EN-seismic Y
For the wind loads, we used the 3D wind option to
calculate with accuracy all zones according to EN1991-
1-4. For the permanent and the snow loads, we used
line forces on beams. The seismic design followed
EN1998.
After the linear and the modal analysis, we conducted
section and unity checks for all the members. We also
proceeded to a serviceability check for the main and
secondary beams.
