Calculate estimated structural dead load from material layers, area, thickness, density, framing weight, and fixed equipment. Use this dead load calculator for floors, roofs, walls, decks, beams, slabs, assemblies, and preliminary structural load planning.
Area dead load:
The calculator multiplies known dead load in PSF by loaded area to estimate total permanent weight.
Material layer weight:
The calculator converts material density and thickness into pounds per square foot, then multiplies by area.
Beam line load:
The calculator converts area dead load into pounds per linear foot using tributary width.
Combined dead load:
The calculator combines known dead load, material layer weight, framing load, finish load, and fixed equipment load.
A dead load calculator helps estimate the permanent weight a structure must support before checking beams, joists, rafters, posts, footings, or foundations.
It can help compare material weight, assembly PSF, total dead load, beam PLF, tributary width, loaded area, and volume.
Your result shows estimated dead load in PSF, total dead load in pounds, beam line load in PLF, material volume, material-only load, framing load, finish load, fixed equipment load, and adjusted load with waste or contingency. These are planning estimates only.
Dead load is the permanent weight of a structure. It can include framing, sheathing, roofing, drywall, flooring, concrete, fixed equipment, and other materials that stay in place.
Convert the material thickness to feet, then multiply density in pounds per cubic foot by thickness in feet. The result is pounds per square foot.
Multiply pounds per square foot by tributary width in feet. For example, 20 PSF over a 10-foot tributary width equals 200 PLF.
No. Dead load is permanent weight. Live load is temporary or movable weight such as people, furniture, stored items, vehicles, or maintenance loads.
