Leave a load blank if not applicable. Multiple cases of a permanent load (D, F, H) add together; multiple cases of a variable load (e.g. Wind X / Wind Y) are alternatives — each generates its own combination variant. Enter loads with their acting sign for uplift checks.

Load Combination Generator
ASCE 7-16/22 (LRFD + ASD)Σ
Enter at least one load value to generate combinations.
Generated combinations are for preliminary design and verification. Verify all factors against the governing code edition and applicable National Annex before use. Results are for educational purposes — always verify with a licensed engineer.
