  1. Seismic Analysis of Structures

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

  3. 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: 11.07.2006 3

  4. where: Eigenfrequency: Damping ratio: Response Spectra viscously damped SDOF oscillator simplified response spectrum From Meskouris (5) From Petersen (2) solving this equation for various w and z, butonly for one specific earthquake, the maximum absolute acceleration of this solution gives us the diagram above

  5. Example: • School building with steel frames or Hyde system Earthquake Engineering Prof. Dr.-Ing. Uwe E. Dorka Stand: 11.07.2006
