摘要：A 3D fracture mechanics model for a 2 × 162m continuous steel truss bridge is modelled by mixing two different element types together, while the cracked cross-beam is meshed as solid elements and 3D-beam elements for the other truss bridge members. The static analysis result show the truss system model works well.
