Example Data Table
| Case | Room | Panel | Loads | Point load | Factors | Output highlight |
|---|---|---|---|---|---|---|
| Sample A | 6.0 x 4.0 m | 0.6 x 0.6 m | Live 7.2, Dead 1.0 (kN/m^2) | 5 kN x 4 items, sharing 2 panels | Impact 1.20, Safety 1.50, Cutouts 5% | Total design load ~ 331.2 kN; intensity ~ 14.53 kN/m^2 |
| Sample B | 10.0 x 5.0 m | 0.6 x 1.2 m | Live 5.0, Dead 1.5 (kN/m^2) | 8 kN x 2 items, sharing 1 panel | Impact 1.10, Safety 1.40, Cutouts 0% | Use to compare point checks against panel rating |

Formula Used
- Floor area: A = L x W
- Total uniform load: Wu = (q_live + q_dead) x A
- Total equipment load: We = P x N
- Design load: Wd = (Wu + We x IF) x SF
- Effective area: A_eff = A x (1 - cutouts%)
- Average design intensity: qd = Wd / A_eff
- Uniform share per panel: W_panel = qd x A_panel
- Point load per panel: P_panel = (P / n_share) x IF x SF
- Pedestal share (simplified): W_ped = W_panel / 4 and P_ped = P_panel / 4
- Utilization: U = demand / capacity (PASS when U <= 1.0)
Distribution varies by system and load location. Use this tool as a screening check.
