Structural calculationPrice on requestWhat is assessed?
For a roof, span, roof weight and wind are important design data. Due to the open sides, wind can affect the structure differently than with a closed building.
A simple appearance still requires appropriate connections and foundations. Determine whether the canopy is free-standing or connected to the house.
What data is needed?
The following information can be used to prepare the assessment. The structural engineer determines whether additional research is necessary.
- Sizes and position
- Roof covering and roof slope
- Material wishes
- Substrate and possible facade connection
What do you receive?
Record the exact delivery in the quotation. Depending on your project and assignment, this involves:
- Calculation of supporting structure
- Basic principles for anchoring and foundation
- Structural details
Discuss who will take care of the architectural development, supplier details and any temporary support. In this way, the components involved are coordinated.
Materials and drawings
The choice of materials and connections follow from the design. Read more about Structural timber and the difference between a architectural drawing and a construction drawing.
How does the process proceed?
You describe your project and share the available data. The assignment, any additional information and planning are then coordinated. Check it out complete step-by-step plan for all phases.
What does your assignment cover?
For an open canopy, wind and anchorage matter alongside self-weight. State whether it is freestanding or attached to a wall. Mention any future side walls now: enclosing it changes the design assumptions.
Can I already order material?
Order structural parts based on the coordinated and current design data. A preliminary estimate is not a complete basis for this.
Is a site visit necessary?
That depends on the project and the available information. Sometimes drawings and photos are sufficient for the inventory; sometimes an admission or additional examination is necessary.
What happens if my plan changes?
Report changes before they are implemented. The structural engineer assesses whether calculations and drawings need to be adjusted.
From data to a detailed plan
Checklist for your application
| Given | What you prepare |
|---|---|
| Sizes and position | Gather the most recent available data and identify what is missing. |
| Roof covering and roof slope | Gather the most recent available data and identify what is missing. |
| Material wishes | Gather the most recent available data and identify what is missing. |
| Substrate and possible facade connection | Gather the most recent available data and identify what is missing. |
- Describe your complete construction plan.
A suitable design for beams, columns and anchoring.
- Discuss missing data.
The structural engineer determines which recording or additional information is required for the agreed assessment.
- Record order and delivery.
Agree on the calculated parts, drawings, price and planning.
- Match the effect to the implementation.
Use the current documents and have relevant changes reviewed before they are implemented.
Frequently asked questions about roofing
What information is required for a roof?
Provide dimensions, free spans, column positions, roof structure and the desired connection to the home. The subsurface and any future additions are also relevant. The open or closed sides influence the wind rating.
Can the canopy be attached to my facade?
That depends on the structural design and the existing facade and supporting structure. Have it assessed where forces can be absorbed. Random attachment to just the facade finish is not a detailed connection detail.
