SBC 301 loads: reference and calculators

All load types in one place, with wind and seismic calculators and fully expanded load combinations for ETABS.

Check before use. Values and formulas follow the ASCE 7 basis that SBC 301 is built on and were not copied from your edition. Saudi city data (wind speed, Ss, S1, TL) is an editable table: only one sourced example row is filled, so enter the rest from SBC 301 or the site report. Most parameters can be edited or overridden by hand.

Units: kN, m, kPa (kN/m²), kN/m³ unless a column says otherwise. Click any number in these tables to edit it (for example to match your SBC edition). Edits last until you reload the page.
