Earthquake Loading lumped MDOF-sytem with rigid
base translation (horizontal case) ground acc. From Clough, Penzien (3) hysteresis law

Reference peak-ground acceleration at Udine: 2.75 m/s2
Stahlbau Grundlagen – Einführung Prof. Dr.-Ing. Uwe E. Dorka Earthquake Engineering Prof. Dr.-Ing. Uwe E. Dorka Stand: 3
4
Response Spectra viscously damped SDOF oscillator
simplified response spectrum From Meskouris (5) From Petersen (2) solving this equation for various w and z, but only for one specific earthquake, the maximum absolute acceleration of this solution gives us the diagram above where: Eigenfrequency: Damping ratio:
