Abstract: |
Regular bridge inspection is of great importance for the reliable use of the traffic infrastructure. This paper describes and explains a method which supports the engineers in the assessment of damaged bridges during or directly after the inspection. Based on this initial estimate, an urgent measure - i.e. a lower permitted bridge class - can be carried out before more detailed inspections and calculations are done. The reliability analyses for the damaged bridges are carried out using first order and second order reliability methods (FORM and SORM). The probability of failure, pf or the safety index β of the system, respectively are the main results of the calculation procedure. |
