FAQ

What is the difference between dead load and live load?
Dead load is the permanent weight of the structure itself. Live load represents transient weights like furniture, occupants, snow, and equipment.
What is L/360 deflection standard?
L/360 means maximum allowable deflection equals span length divided by 360 (e.g. 0.4 inches for a 12-foot span under live load).
What safety factor is used in structural design?
Structural engineering design uses safety factors ranging from 1.5 to 3.0 depending on load uncertainty and material ductility.
