|Title:||Elastic and inelastic seismic response of buildings with damping systems||Authors:||Ramirez, Oscar M.

|Keywords:||Damping (Mechanics);Earthquakes;Seismology||Issue Date:||2002||Publisher:||Earthquake Engineering Research Institute||Source:||Earthquake spectra, 2002, Volume 18, Issue 3, Pages 531-547||Abstract:||The effect of damping on the response of elastic and inelastic single-degree-of-freedom systems was studied by nonlinear response-history analysis using earthquake histories that matched on average a 2000 NEHRP spectrum on a stiff soil site for a region of high seismic risk. New displacement reduction factors for levels of damping greater than 5% of critical are presented. New equations to relate inelastic and elastic displacements in the short-period range, for levels of damping greater than 5% of critical, are presented. The technical basis for reducing the minimum design base shear in damped buildings by a maximum of 25%, from that required for the corresponding undamped building, is derived based on comparable levels of damage in both the damped and undamped buildings.||URI:||http://ktisis.cut.ac.cy/handle/10488/7720||ISSN:||87552930||DOI:||10.1193/1.1509762||Type:||Article|
