Calculation reports
Create Struxt3D calculation reports for the whole model or one member, slab, wall, joint or footing, with step-by-step calculations, and export them to PDF, Word or HTML.
A design is only as useful as your ability to show how it was reached. Struxt3D writes a paginated calculation report from the design: the design basis, the analysis, every element's result and, when you ask, the step-by-step calculations with the formulas, values and code clauses. You can write it for the whole model or for a single element, read it in the app, and print it, save it as PDF, or download it as Word or HTML.
Reports describe a design, so they need one: run the design first with F6. Before that, the report buttons are greyed out. If you change the model afterwards, design again before writing the report.
Opening a report
| Where | Report |
|---|---|
| Results summary › Calculation report (Simple) | Whole model |
| File › Calculation report… or Design › Calculation report… (Full) | Whole model |
| File › Report of the selection… or Design › Report of the selection… (Full) | The selected member, node or footing |
| Member or node inspector › Calculation report | That member, or that joint and its connections |
| Footing card or properties › Footing report | That footing |
The report opens full-height over the app, with a cover, a contents page with page numbers, numbered sections and A4 pages. Close it with the × button or Esc.
The report bar
- Summary | Detailed calculations — the summary has the tables and results; the detailed version adds the step-by-step calculations.
- Report for — switch between Whole model and any one element, grouped as Members, Slabs and plates, Walls, Footings and Joints. Each entry shows its section or size and its ratio. Type to find one.
- Zoom − and +, with the zoom level between them.
- Print — print the report, or choose Save as PDF as the printer to make a PDF.
- Word — download a Word document (.docx) you can edit.
- HTML — download the report as a web page.
While a report is being written, the bar says so — Writing the calculations…. Detailed reports of large models take a few seconds.
The whole-model report
The report for the whole model has these chapters:
- Design basis — the design code and the standards it uses, the materials with their strengths, moduli and densities, the member groups and sections, the slab and wall thicknesses, the loads, and every load combination with its factors (ULS for strength, SLS for service).
- Analysis — the model's size, base reactions per load case, the largest displacement under the service combination and, with earthquake on, the vibration modes with their periods and mass shares.
- Design chapters for each kind of element in the model: steel or timber members, concrete beams and columns, slabs and plates, shear walls, footings, steel connections and composite floors. Elements are grouped — members by group and section, slabs by kind and thickness, footings by size — and each group lists every element in a table with its governing check, combination and ratio.
- Notes — warnings from the analysis and design: what was assumed, simplified or could not be designed.
In Detailed calculations, the governing element of each group is written out in full, step by step. For concrete this is the span or storey that governs a beam line or column stack, the governing slab panel, and the governing footing. The most utilized connection of each type and size is shown in full with its drawing.
Element reports
A report of one element contains the design basis, then that element alone in full:
- Member — its data (section, material, length, restraints), its internal forces in each combination, and its design: for steel and timber the governing combination's checks clause by clause; for concrete the beam span or column storey calculation, with bars and links. Its end connections and, for composite beams, the composite design follow.
- Slab or wall panel — the reinforcement design of that slab or that storey of wall, with punching shear where columns are.
- Joint (node) — every steel connection at the joint with its drawing, parts, forces and checks.
- Footing — the footing's data, the support reactions in each combination, and the footing calculation: sizing for bearing, bending, shear and punching, and the bars.
Element reports always include the step-by-step calculation. They are the quickest way to answer “why did this member get this section?”.
Tips
- Give the project a name before writing a report: it appears on the cover and in the file names.
- The cover shows a picture of the model as it is in the 3D view, so frame it first.
- Use the Word export when you need to add your own pages, a company template or signatures.
- For drawings of the design, see Shop drawings.
