The ClearCalcs open-web steel joist (OWSJ) calculator is a user-friendly and efficient tool that enables engineers to swiftly design and analyze open-web steel joists (also known as bar joists) according to industry standards such as the Steel Joist Institute's SJI Load Tables. With easy data entry and dynamic load linking, engineers can quickly assess the adequacy of open-web steel joists, accompanying columns, and connections. By streamlining calculations and automating repetitive tasks, this calculator optimizes productivity and facilitates the exploration of different design configurations, ensuring reliable and efficient open-web steel joist systems.

Steel joist design software to American standards

Easily design and analyze open-web steel joists (also known as bar joists) according to industry standards such as the Steel Joist Institute's SJI Load Tables.

Easy-to-use steel joist calculator for K-series and LH-series open web steel joists

Use Steel Joist Calculator to quickly size steel joists and check for the moment and shear utilization from a database of thousands of sections. All values are retrieved from SJI 100-2020.

Intuitive inputs for steel joists load calculations

Easily input the distributed loads, line loads, point & moment loads, as well as center-to-center spacing or tributary width to quickly calculate the capacity of steel joists.

Color-coded utilization checks for steel joists moment, shear, and deflection calculation

The all-in-one Steel Joist Calculator lets you check allowable bending moment, shear, deflection, as well as maximum line load and point load utilization at a glance with our traffic light checks.

With spreadsheets and clunky software

Frustration, fuss, and fragile formulas—the old way of engineering calculations that holds you back.

Struggle with endless spreadsheets and custom formulas.

Building codes change, but outdated software and spreadsheets don’t.

Triple-check and verify manual input at every turn.

Old software feels like a maze, with unclear settings, limited templates, and rigid interfaces.

How it works

Your code-compliant calculator

Tired of complex calculations? ClearCalcs Calculator Library keeps it simple, secure, and code-compliant—so you can calculate with confidence.

Save time with ready-to-use templates for wood, steel, and concrete

ClearCalcs offers an extensive library of easy-to-use calculators for beams, columns, and footings, designed to make structural calculations simpler and faster.

Choose from a wide range of pre-configured beam and column options, complete with automatic member sizing, so you can quickly reach reliable designs and reduce rework.

Beams

Columns

Foundations

Walls

Loads

Dynamically track your load paths from roof to foundation

No need to copy and paste reactions between calculations! If the top calculator's reactions change, the loads being inherited onto the lower calculator will update automatically. This includes all loads such as dead, live, snow, seismic, and wind.

Submit professional reports for permit review

ClearCalcs is not only easy to use, but also easy to check! All calculations follow an easy to understand traffic light check system, with multiple levels of detail available giving you the choice of printing every step of the calculation and all code and standard references, or simply a compact, one-page print out.
