Understanding and Simulating Human-Induced Vibrations on Footbridges in SOFiSTiK FEA

Analysis, Guides

In this informative presentation, Wojciech Pruszkowski, SOFiSTiK AG, explores various dynamic finite element simulation methods, starting from static loading scenarios and progressing to dynamic simulations with moving load analyses. Wojciech will walk you through the step-by-step process of applying these techniques to effectively simulate and understand the dynamic challenges that footbridges face.

This video aims to define the problem along with its basic underlying theory and presents the solutions possible within SOFiSTiK.
