Dead and Live Loads module

Free Dead and Live Load Calculator — ASCE 7-22 Table 4.3-1 and Table C3.1-1a

Build dead and live loads per ASCE 7-22. Assemble dead loads from material and assembly weights (Table C3.1-1a) for roofs, floors, walls, and ceilings; assign live loads by occupancy (Table 4.3-1), including the roof live load Lr, at the tabulated values — a reduced live load is entered if one is taken — and summarize them as the project's gravity loads.

Free to use with no sign-up: the calculator runs in full in the browser with no account, no trial and no feature limits, and the full detailed calculation is shown on screen, step by step, with the code sections and tables it draws on, so it can be checked by hand. A free account keeps one project in the cloud; unlimited cloud projects and printing the report to PDF are Pro features.

What the calculator includes

  • Dead loads built component by component from ASCE 7-22 Table C3.1-1a for a roof, a ceiling, any number of floors, interior and exterior walls, with the whole table to pick from in its own order and categories and thickness-priced items scaled by the thickness entered.
  • Light, Typical and Heavy presets for every assembly, a duct allowance for floors and ceilings, and user-defined lines such as rooftop PV, with each assembly's total dead load D in psf.
  • Live loads by occupancy from Table 4.3-1, shown in full in the book's order and columns, including the roof live load Lr and the handrail loads of §4.5.1; a Residential preset of eight rows; live-load reduction is not applied, so a reduced live load is entered if one is taken.
  • The summary becomes a calculation section of the printed report, first in the default order, and reorders with the dashboard.

In every StructSuite module

  • The code clause behind a value is quoted verbatim beside it from a blue book icon — NDS 2024, SDPWS 2021, AISC 360-22, ACI 318-25, ASCE 7-22 and the 2024 IBC, FEMA P-750 and the I-joist manufacturer's technical bulletins — so the standard does not have to be opened to check it.
  • A missing input stops the calculation rather than being filled in silently, and judgment choices start unselected.
  • Where a limit applies it is checked as you type: beam RB and column ℓe/d, steel Lc/r, rebar ratios and spacing, fy and f′c.
  • Every module prints into one calculation report (Pro) with a cover sheet, a table of contents with measured page numbers and a verification link a plan checker opens without an account.

Frequently asked questions

Where do the dead and live load values come from?

Dead loads are assembled from material and assembly weights in ASCE 7-22 Table C3.1-1a for roofs, floors, walls and ceilings. Live loads are assigned by occupancy from Table 4.3-1, including the roof live load Lr, at the tabulated values; live-load reduction is not applied, so a reduced live load is entered if one is taken.

Does the result go into the calculation report?

Yes. The load summary becomes a section of the project's report, first in the default order. Printing the report to PDF is a Pro feature; the calculation itself is free on screen.

Do the loads feed the other calculators?

No. Each member calculator takes its own loads. This module is the project's load schedule: the dead-load assemblies with their components and totals, and the live loads by occupancy, printed as the first section of the report.

Is the dead and live loads calculator free?

Yes. Free to use with no sign-up: the calculator runs in full in the browser with no account, no trial and no feature limits, and the full detailed calculation is shown on screen, step by step, with the code sections and tables it draws on, so it can be checked by hand.
