Abstract

Abstract In this study, non-linear behavior of steel frames with dual lateral loader system with convergent crossing and chevron bracing equipped with linear and non-linear liquid viscose dampers in 8 and 12 story models as 2D under the record of near and far field to fault earthquakes are studied, evaluated and compared. For doing time history non-linear analyses, non-linear analysis software of Perform-3D has been used. This research absolutely confirms that viscose dampers reduces structure's responses under the effect of near and far field to fault records in a way that using non-linear viscose dampers in dual steel frames, the rate of created reduction is under the effect of near field records and more.
