Fatigue Load Model 4, Lorry Type 4 for Quadruple Axle Load Analysis
Fatigue Load Model 4 shows a quadruple axle load scenario for stress spectrum analysis according to EN 1991-2:2003 Section 4.6.5.
The image illustrates a fatigue load model 4 designated for a type 4 lorry assessed under a quadruple axle load. This model is used for verifying the stress spectrum necessary in ultimate limit state design. The configuration adheres to the specifications in EN 1991-2:2003 Section 4.6.5, offering guidance for structural assessment under dynamic load conditions. It serves as a reference for engineers in bridge design and assessment.
