Scope & assumptions
Simply supported beam under full-span UDL. The calculator evaluates beam demand and compares it with transparent resistance screens based on user-entered CSA resistance/stability modifiers.

Calculation basis
Mf = qf·L²/8; Vf = qf·L/2; Mr,screen = φ·β·Fy·W; Vr,screen = φ·kv·Fy·Av; w = 5·qser·L⁴/(384·E·I).
Important engineering note: CSA S16:24 member classification, lateral-torsional buckling, web slenderness/buckling, concentrated loads, holes, fatigue and combined actions are not automatically derived. Verify β, kv and all code limits to CSA S16:24 including current updates.

Frequently asked questions
Is this a complete code design?
No. It is a transparent preliminary calculation. Code-specific limits, detailing, stability and project conditions must be verified independently.
Can I use the result for construction?
Use the result as a screening or checking aid only. Final design and construction documents should be verified by a qualified professional where required.
Why are some resistance factors entered by the user?
Many design standards contain member-, material-, product- or project-specific values. Metric Republic keeps these visible and user-controlled instead of hiding assumptions.
