Loading, Load Cases & Load Combinations - Loading And Load Combinations
Create auditable STAAD load cases, mass definitions, signed wind/seismic actions, member/floor/element loads, combinations, envelopes, and repeat-load workflows without hiding the governing design basis.

Positive D and L act downward. W↑ is entered as a positive uplift magnitude, so it must subtract from downward gravity action.

Net line load
44.0 kN/m
Net action is downward.
Design-basis note: These three combinations are deliberately limited teaching examples for sign conventions and load-factor mechanics. A real STAAD model must use the project's governing code, edition, load categories, and required combinations.
