Footbridges Load Tests in Poland: History, Regulations, Examples, Results

Abstract

<p>The paper presents some chosen results of footbridges tests on site that have been done by the authors, recently. Dynamic amplification factor, natural frequency, mode shapes and damping have been analyzed by dynamic footbridges testing. The paper describes also the dynamic method of the suspension control system forces. As the result of registration and analysis of free vibration of a suspender, the authors present quick, non-destructive and reliably test as the contemporary method to improve safety of arch and suspended footbridge superstructures.</p>
