Floor Joist Analyzer Pro

Floor Joist Analyzer Pro v2.0

Review a proposed floor joist span directly in AutoCAD. Select two clear-bearing points, choose a joist type, and enter the loads and material values for a preliminary simple-span check.

Features include:

• Solid-sawn lumber, TJI series, and other engineered I-joist options.
• Live-load, dead-load, and optional point-load inputs.
• Preliminary bending or moment, shear, and deflection checks.
• An optional joist-line estimate from the bay width and spacing.
• A report you can place in the drawing or export as a TXT file.

Download includes: the AutoLISP routine, DCL dialog, and installation instructions. Designed for AutoCAD 2002; enter JOISTCHECKPRO after loading the routine.

Results depend on the values you enter. Verify engineered-joist capacities against current manufacturer data. This preliminary check does not replace span tables or structural engineering review.
