Use case

Screen beam stiffness before design review.

Get estimated max deflection and span ratio for quick feasibility checks.

Trusted inputs

Euler-Bernoulli beam equations

Range notes

Supports uniform load and point-load screening cases.

Constant section assumption.

Serviceability ratio is configurable because project limits vary by code and load case.

Important

Engineering estimate only. Validate with full structural analysis before approval.
