Occupancy Charge
Live Charge Calculatrice
Use this page when the ingenierie question starts from imposed loading. Pick a planning occupancy preset or type your own area charge, then convert it into the poutre charge model you need pour the next step.
Occupancy Entrees
A light planning setup pour domestic floors where the imposed charge remains modest.
Residential Room Starter: A light planning setup pour domestic floors where the imposed charge remains modest.
Live Charge Summary
Occupancy note
- Characteristic live charge: 2,00 kN/m^2
- Planning reduction factor: 1,00
- Applied live charge: 2,00 kN/m^2
Calculation Basis
Assumptions & Limits
- Starter occupancies et reduction factors remain project hypotheses et do not replace the governing code.
- The page prepares charge entrees but does not apply full design combinations or code partial factors automatically.
- Changing tributary width, local peaks, or an uncertain charge path require a more detailed model.
Reference Basis
Reference Occupancy Starters
| Best use | Early occupancy-based beam loading before code combination checks |
| Primary output | Applied live load in kN/m^2 and converted line load in kN/m |
| Reduction factor | Manual project assumption; not an automatic code reduction engine |
| Model scope | Service-load planning and beam input preparation |
Notes techniques
- Starter occupancies are planning defaults only. The governing project standard et local building code still control the final imposed charge.
- The reduction factor is shown explicitly so the user can document the hypothese instead of hiding it in the calculatrice logic.
- If occupancy, storage intensity, or movable partitions are uncertain, keep the reduction factor at 1.0 until the design basis is settled.
Calculation Method
- Applied live charge: q_applied = q_k x psi. The page multiplies the entered or starter imposed charge by a user-controlled planning factor.
- Line charge: w = q_applied x b_tr. The resulting line charge is the value to carry into a poutre response page.
- Member charge: W = w L. This gives a fast service-level total live charge on the member.
Questions frequentes
- Does this page replace the governing building code? No. It is a transparent planning calculatrice. The final imposed charge still has to match the standard et occupancy category used on the real project.
- Why is the reduction factor manual? Because live-charge reduction depends on jurisdiction, use case, et design basis. Making it explicit is safer than hiding a code hypothese inside a generic page.
- When should I keep the factor equal to 1.0? Keep it at 1.0 whenever the occupancy is still uncertain, the charge is already code-governed, or you are preparing a conservative service-charge check.
