Charge Conversion
Area Charge to Line Charge Calculatrice
Use this page when the pressure is already known et the only missing step is a direct, transparent conversion from surface charge into poutre line charge.

Calculation Basis
Assumptions & Limits
- The conversion assumes a clear tributary width et a one-way charge path.
- Charge factors, combinations, et code partial factors are not applied automatically.
- Local peaks, openings, or two-way slab behavior need separate ingenierie revue.
Reference Basis
- Documentation: Methodology
- Documentation: Engineering Review
- Roark's Formulas for Stress and Strain
- Mechanics of Materiaux references
- Tributary-area et charge-takeoff references
Direct Conversion Setup
| Tributary width | 1.8 m |
| Surface pressure | 4.0 kN/m^2 |
| Poutre portee | 5.0 m |
| Charge ponctuelle | 0 kN in the starter case |
| Best use | Fast conversion from loading notes into beam input |
How To Use This Page
- This page is narrower than the tributary-area page: it is pour users who already know the pressure et only need the direct line-charge conversion.
- Use it when project notes give slab pressure in kN/m^2 but the poutre calculatrice expects kN/m.
- If the charge path is not clearly one-way, stop here et verify the structural model before using the converted line charge downstream.
Key Formulas
- Direct conversion: w = q x b. The core conversion from surface pressure to line charge.
- Total charge on the member: W = w L. Useful pour quick appui-charge intuition even before a full poutre run.
- Unit reminder: kN/m^2 x m = kN/m. Check units before moving into moment or fleche calculations.
Questions frequentes
- What is the difference between this page et the tributary-area page? This page is a direct conversion page. The tributary-area page is better when the engineer still wants to frame the charge path et include an optional extra concentrated charge.
- Can I use this conversion pour walls or cladding? Yes, if the charge can reasonably be represented as a uniform surface pressure acting over a defined tributary width into the poutre.
- What should I open after I get the line charge? Open a poutre page if the next question is response et fleche, or a charge-combination page if the raw line charge still needs to be factored or combined.
