Beams & Spans
Tools for beam loads, deflection, spans, steel beams, wood beams, LVL beams, and I-beams.
About these structural calculators
These structural calculators are designed for fast estimating, planning, and educational use. They can help with common construction and engineering calculations such as beam loads, beam deflection, joist spans, roof framing, footing sizes, column loads, support reactions, bending moments, section modulus, stress, steel weight, and rebar needs.
Common uses
Use these tools to plan beam and span layouts, compare loads, estimate framing materials, check deck and support spacing, calculate foundation and footing requirements, and work through basic structural math before starting a project or reviewing measurements.
Important structural safety note
Structural projects can involve building codes, load requirements, soil conditions, material grades, deflection limits, safety factors, and local engineering rules. Use these calculators as planning estimates and verify important load-bearing decisions with a qualified professional before building, modifying, or removing structural components.
