Draw a glulam portal, roof truss, floor joist, bearer, deck or pergola on the grid, load it, and see it analysed for every load combination as you draw. Each member is designed to AS 1720.1 with φ by category, k1 by load duration, k4, k6, k9, the k12 stability factor and creep — bending, shear, compression, tension, combined actions and long-term deflection — and can be auto-sized. Then estimate the timber, treatment, labour, connections and footings, print A3 drawings and export a PDF calculation report, Excel, DXF and JSON.
Preliminary design: characteristic values are typical published values — confirm against AS 1720.1 and your supplier; joints, bearing and notches are not checked. Rates are indicative.
Start from a glulam portal, floor joist, continuous bearer, Fink roof truss, deck, pergola or lintel, or draw your own frame. Choose MGP10, MGP12, F5 or F17 sawn timber, F17 posts, GL13, GL17 or GL21 glulam or LVL, in one to three nailed pieces.
Members are designed to AS 1720.1 with the capacity factor φ for the structural category, k1 for the load duration of each combination, k4, k6, k9 strength sharing and the stability factor k12 from the slenderness coefficients S1, S3 and S4. Bending, shear, compression, tension, combined actions and long-term deflection with the creep factor j2 are all checked.
