The carport structure has been designed in accordance with the following standards prescribed for structures of this type:

● EN 1990; Eurocode 0: Basis of Structural Design
● EN 1991-1-1; Eurocode 1: Actions on structures – Part 1-1: Densities, self-weight, imposed loads for buildings
● EN 1991-1-3; Eurocode 1: Actions on structures – Part 1-3: General actions – Snow loads
● EN 1991-1-4; Eurocode 1: Actions on structures – Part 1-4: General actions – Wind actions
● PN-EN 1992-1-2; Eurocode 2: Design of concrete structures – Part 1-1: General rules and rules for buildings
● PN-EN 1993-1-1; Eurocode 3: Design of steel structures – Part 1-1: General rules and rules for buildings
● EN 1993-1-3; Eurocode 3: Design of steel structures – Part 1-3: General rules Supplementary rules for cold-formed members and sheeting
● EN 1993-1-8; Eurocode 3: Design of steel structures – Part 1-8: Design of joints

Compliance with the above standards and criteria guarantees the safety of the entire structure, the use of the right materials and the fulfilment of standards in terms of loads or weather resistance.

During the design process, all factors and criteria necessary to plan and prepare a carport structure for multiple use were taken into account.
The typical Carport design requires due adaptation to local conditions in terms of compliance with assumed climatic loads and accepted foundation conditions.

The project was carried out based on the following assumptions:
● Roofing load
● Trapezoidal steel sheet ° – 0.05 kN/m2
● Load on the photovoltaic system – 0.25 kN/m2
● Climatic loads – snow
IV snow load zone adopted (sk= 1.6kN/m2, μ1=0.8)
● Climatic loads – wind
II wind load zone adopted (vb.0=26m/s, terrain category II)

Given the assumptions made for the project (described above in the question „What assumptions were made for the Carport structure”) the allowable loads are:

Carport prepared for trapezoidal sheet metal roofing:
0.05 kN/m2

Carport prepared for photovoltaic roofing:
0.25 kN/m2

Carport prepared for a polycarbonate roofing:
0.05 kN/m2

For design purposes and bearing in mind the EN 1991-1-3; Eurocode 1 standard, the shed structure has been prepared taking into account the snow cover load of stage 4*. This means the structure can withstand significant snow loads 

(sk= 1.6kN/m2, μ1=0.8)

The carport was designed as a compliant structure:
ISO 12944-2 – Corrosivity category for steel construction
ISO 12944 is concerned with the classification of environments according to their corrosivity, i.e. the ability of an environment to cause corrosion, in a specific corrosion regime, caused by the action of corrosive agents. The standard specifies corrosive exposures caused by the action of the atmosphere, soil and water. On a 6-point scale that determines corrosivity, Carport meets the standard for environmental aggressiveness:
C3 – average
relating to outdoor structures and covering urban and industrial atmospheres where there is medium SO3 sulphur oxide pollution and low salinity coastal areas.

The carport is manufactured from materials that meet the following standards:
Construction and contractor classification

● Consistency class of steel construction: CC1 according to EN 1990
● Category of use: SC1 to EN 1090-2
● Production category: PC1 to EN 1090-2
● Steel construction class: EXC1 according to EN 1090-2

The design of the shed structure assumes the possibility of its construction with solid panels along three sides (loads from pressure and wind suction were taken into account in the static and strength calculations).

Structural steel components in Execution Class EXC1
(according to EN 1090-2 tab. B.3)

The performance class was selected based on the following assumptions:

● Destruction consequence class CC1
● Use category SC1
● Production category PC1The carports on offer are not fitted with roofing.
