About this calculator

Use case

Screen beam stiffness before design review.

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

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.
