Failure of steel truss bridge members could lead to a further damage or even to the collapses of the bridge. The collapse of a bridge often occurred in Indonesia due to various factors, such as over loads, dynamic live loads, earthquake and deteriorated material. Push-over analysis was used to analyze the failure mechanism of a steel truss bridge, which gave a point load at the mid-span and to be gradually increased. Six models of the bridge were analyzed, which are three continuous span and three single span bridge models. The study shows that the failures of the continuous steel truss bridge occurred in the diagonal chord of the end portal. All single span bridge models failure occurred on the chord at the mid span. The performance level of structure shows all models of the truss bridges are in the Immediate Occupancy (IO) based on the target displacement of FEMA 356. The actual ductility occurred in all models of bridges is compliant with Indonesian Standard.
