Power Spectral Density (PSD) is an essential technique for analyzing acceleration signals, helping to identify dominant frequencies and structural resonances. This guide explains the steps to compute PSD, different estimation methods, and its applications in engineering.
Understanding how high-performance computation (HPC) supports real-time structural health monitoring (SHM) by enhancing data acquisition, signal processing, damage detection, and decision-making.
Earthquakes shake buildings in all three directions, but why is vertical motion often ignored in design? Thanks to gravity, high vertical stiffness, and built-in safety margins, structures are naturally robust in the vertical direction. However, certain components and seismic codes still require careful consideration. Learn when vertical effects matter and why horizontal motion is more critical.
