| | Summary: |
| | Presented in this paper is the vulnerability of road bridges typical for the Republic of Macedonia through analytical vulnerability curves. The typical bridges were selected on the basis of the performed inventory study within which statistic analysis of in situ collected data on all vital structures along the national roads and high-ways in the territory of RM was carried out. The results from the performed statistic analysis show that most of the bridge structures represent reinforced concrete girder bridges. To define their vulnerability, there were selected representative examples with variable geometrical characteristics whose values were adopted in combination with the values obtained from the statistic analysis. The vulnerability curves were obtained analytically, applying the multiple stripe analysis method. Numerous nonlinear analyses were performed with real time histories. PGA was used as a measure of intensity. Based on the nonlinear behaviour of the bridge and the development of displacements in the bearings, four levels of damage were defined. |
