Design & analysis toolkit

The complete calculation library, organised like Tekla Tedds and GEO5: steel, concrete, timber and masonry design, foundations, retaining walls and slopes, ground engineering, site investigation, pavements and traffic, hydraulics, bridges, and analysis and loading. Each calculation runs in your browser, shows its formulas, pass/fail checks and a drawing with standard engineering hatching that redraws as you type, and exports a live-formula Excel workbook.
