Course Moving Load Train – Dynamic Analysis

This course introduces modal analysis and eigenvalue extraction in SOFiSTiK FEA, referencing EN 1991-2, Section 6.4.6, and UIC Code 776-2, Section A.6.1.

You will learn how to define the structural system, prepare the model for dynamic analysis, calculate eigenmodes, and interpret results correctly. Step by step, you will understand how stiffness, mass distribution, and boundary conditions influence structural vibration behaviour. The course combines theoretical fundamentals with practical workflows, enabling you to confidently perform eigenvalue analyses for railway bridge verification and dynamic compliance with European standards. You will also learn how to calculate eigenfrequencies and mode shapes, define load trains, perform dynamic analyses for train passages, and postprocess results using time histories and envelopes.
