Elastic Response Spectra: Fundamentals

This lecture covers the elastic response spectra, a crucial tool in seismic design. It explains the computation of response spectra, the relationship between different spectral values, and the effect of damping on spectral values. The instructor discusses the significance of peak ground acceleration, the calculation of pseudo-acceleration, and the impact of damping ratio on spectral values. Additionally, it explores the behavior of very rigid and very flexible structures in relation to spectral values. The lecture also delves into inelastic response spectra in design codes, providing an example of calculating peak force and displacement for a bridge pier.
