Assessment of structural condition of steel bridge in Brandýs nad Orlicí

Abstract

This paper deals with structural condition assessment of historical steel through arch bridge in Brandýs nad Orlicí. Structure was dynamically tested to obtain mode shapes and eigenfrequencies on non-loaded structure and to estimate logarithmic damping decrement after traffic loading. Material properties were verified. Calculation model was created to validate its statical and dynamical behaviour. Article focuses on comparison of calculated results and properties of real structure upon excitation.
