Resum
This paper presents a methodology for the load capacity evaluation of existing railway bridges based on the quantification of their robustness. The proposed technique uses the results of a non-linear structural analysis of a bridge system and couples the analysis with modified member and system reliability evaluations in order to assess the bridge’s robustness and its overall system capacity. Bridge robustness is measured by the so-called redundancy factors, which serve to compare the system...
