| Abstract [eng] |
Most of the structural calculation methods in Civil Engineering are implemented for the case of static loads. However, in the real world static loads do not exist. All loads are constantly changing with time. Therefore, it is crucial to consider dynamic load effects on building structures, which may considerably differ from static effects. Impact loading is one of the most dangerous dynamical situations in construction. Impact loads act quite suddenly and with large accelerations. Therefore, impact provokes considerably more hazardous internal forces and deformations in structural elements, as compared to static forces. The most simple and most widely used method to describe impact load effects is the dynamic factor kdyn, which shows the ratio between dynamic and static deformations. In this research the deformations of a cantilever metal beam are analyzed. Both static and dynamic loading experimental measurements are compared with theoretical results. Different dynamic factor calculation methods are compared with experimental results. Finally, a statistical analysis of the errors of the experimental measurements is carried out. |
