Typical floor live load values by occupancy
Floor live load depends on use, and codes set minimum values by occupancy. Here is a reference table for offices, homes, retail, storage and more, in kPa and psf.

Roof live load vs snow load
A roof carries both a minimum roof live load and a snow load, and the larger governs. Here is the difference, how each is found, and which one to design for.

Tributary area vs influence area
Tributary area is the floor that loads a member; influence area is the larger area whose load affects it. Here is the difference, the K_LL factor, and why it drives live load reduction.

Dead load vs live load, explained
Dead load is the permanent weight of the structure; live load is the movable weight it carries. Here is the difference, typical values, and how each is factored.

ASCE 7 live load reduction, explained simply
A column carrying ten floors is not realistically loaded to the full design live load on every one at once. ASCE 7 lets you take credit for that. Here is the formula, the K_LL factors, and a worked reduction.

Partition load allowance explained
Movable partitions are covered by a load allowance rather than counted one by one. Here is what the allowance is, typical values, and when a partition is counted as dead load instead.
