Capacity AnalysisStructural Capacity (C)100 kips
Dead Load (D)30 kips
Live Load (L)40 kips
Dynamic Allowance / Impact (IM)33%
Rating Factor (RF)1.32SAFE (Passes Load Rating)

C = 100
L+IM
D
D = 30
L+IM = 53.2
L+IM = 53.2
If Demand (D + L + IM) exceeds Capacity (C), the Rating Factor drops below 1.0, and the bridge is considered structurally unsafe for that load.
