STUDY ON PRACTICAL APPLICATION OF DAMAGE TOLERANT STRUCTURES WITH SEISMIC CONTROL PANEL USING LOW-YIELD-POINT STEEL TO A HIGH-RISE STEEL BUILDING

Abstract

A damage tolerant structure (DTS), which is primarily aimed to control structural damages during large earthquakes, has been developed as a new seismic-damage-controlled structure. A practical design application of DTS to a high-rise steel building in Oita city, Japan is investigated. DTS has a main frame whose allowable elastic-deformation is aimed to be larger, and also has seismic control panels using low-yield-point steel as dampers. As results of response analyses on DTS against large (level 11) earthquakes, dampers can well work to keep main frame within elastic response and also can exhibit enough energy absorbing capacity to sustain required performance even after earthquake.
