| Abstract: |
Considering the management of highway bridges in service under severe conditions for more than 100 years, evaluation of safety is indispensable. By adopting design formulae, it is possible to evaluate the safety quantitatively without complicated processes. However, to adopt a formula from the design, the structure needs to satisfy the Navier hypothesis and other requirements. For these reasons, the authors carried out an examination of evaluation procedures to define the limit deterioration state of PC structures for adopting a design formula. By comparing evaluation results of a design formula and experimental results of an actual PC beam removed from service, and also nonlinear FEM analysis results, the study shows the limit deterioration state of PC structures for adopting a design formula for the evaluation of safety. |
