Structural calculationPrice on requestWhat is assessed?
A truss forms a coherent supporting structure. The shape, span, load and connections determine how forces are distributed and transferred to the foundation.
The stability outside the plane of the truss and the cooperation with the roof and facades are also important. The development of connections is defined in the assignment.
What data is needed?
The following information can be used to prepare the assessment. The structural engineer determines whether additional research is necessary.
- Geometry and supports
- Roof and facade weights
- Use of the building
- Mounting and connection requirements
What do you receive?
Record the exact delivery in the quotation. Depending on your project and assignment, this involves:
- Calculation of the truss
- Profiles and material data
- Connection development within the assignment
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 Steel 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 a steel frame, joints and bases form part of the structural model. Supply required clear space and bracing positions. Agree the division between primary structural design, connection design and the steel fabricator’s drawings.
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 |
|---|---|
| Geometry and supports | Gather the most recent available data and identify what is missing. |
| Roof and facade weights | Gather the most recent available data and identify what is missing. |
| Use of the building | Gather the most recent available data and identify what is missing. |
| Mounting and connection requirements | Gather the most recent available data and identify what is missing. |
- Describe your complete construction plan.
Bring together beams, columns and connections in a design for your roof or building.
- Discuss missing data.
The structural engineer determines which site survey or additional information is required for the agreed assessment.
- Record order and delivery.
Agree on the calculated parts, drawings, price and planning.
- Coordinate the design with the construction work.
Use the current documents and have relevant changes reviewed before they are implemented.
Frequently asked questions about steel truss
Which parts are included in a truss calculation?
This concerns the agreed bars or profiles, nodes, support and coherence with the stability structure. Ask which connections and foundation reactions are being developed and who will provide supplier and assembly information.
Can an existing truss support additional installations?
That depends on the truss, the position of the new load and the existing design principles. Provide device weights, suspension points and any dynamic effects. Also have the connecting construction defined within the required assessment.
