How It Works!

Step 1: Calculate truss height

Step 2: Calculate total bottom chord length and half truss span

Step 3: Calculate top chord length

Step 4: Calculate bay spacing and initialize arrays

Please use the truss members calculator and the purlin length calculator to get the total truss member length and the total purlin length.
