Title

NONLINEAR FINITE ELEMENT ANALYSIS OF STEEL SHEAR WALLS EQUIPPED WITH YIELDING ADAS DAMPERS

Pages

  -

Abstract

 IN THE PAST TWO DECADES, STEEL PLATE SHEAR WALLS HAVE BEEN USED IN A NUMBER OF BUILDINGS IN JAPAN AND NORTH AMERICA AS THE LATERAL LOAD RESISTING SYSTEM. BECAUSE OF SOME ADVANTAGES OF THIS STRUCTURAL SYSTEM, MORE TENDENCY FOR APPLICATION OF THIS SYSTEM IS OBSERVED IN THE PAST FEW YEARS. HENCE, IMPROVEMENT OF THE PERFORMANCE OF STEEL SHEAR WALL SYSTEMS IN EARTHQUAKES WAS ALWAYS AN IMPORTANT FILED OF INTEREST IN RESEARCH CENTERS. THIS PAPER PRESENTS A NEW METHOD OF RESPONSE ENHANCEMENT FOR STEEL PLATE SHEAR WALLS BY USING YIELDING DAMPERS, WHICH IMPROVES THE ENERGY DISSIPATION OF THE STEEL SHEAR WALL. THE STUDY PRESENTS AN INNOVATIVE CONFIGURATION FOR STEEL PLATE SHEAR WALLS TO IMPROVE THEIR ENERGY ABSORPTION IN THE SEISMIC EVENTS. AN EXISTING BUILDING LOCATED IN TEHRAN WAS SELECTED AND THE GEOMETRY OF A STEEL SHEAR WALL IN ITS GROUND FLOOR WAS EXTRACTED FOR EVALUATION PURPOSES. MICRO SCALE FINITE ELEMENT MODELS WERE DEVELOPED FOR THE GEOMETRY, USING ABAQUS SOFTWARE, TO ANALYZE THE EFFECTIVENESS OF ADDING DIFFERENT YIELDING ADAS DAMPERS TO THE SYSTEM ON THE SEISMIC RESPONSE OF SYSTEM. IN PARTICULAR, THE STUDY IS FOCUSED ON THE EFFECTS ON MAXIMUM DRIFTS, PERIOD OF THE STRUCTURE, MAXIMUM ACCELERATION AND BASE SHEAR, AIMING TO PROVIDE INFORMATION ON MAIN RESPONSE PARAMETERS TO BE ADDED TO THE EXISTING KNOWLEDGE. BY EVALUATION OF FINITE ELEMENT RESULTS, IT WAS FOUND THAT THE PROPOSED SYSTEM PERFORMED WELL IN CONTROLLING THE MAXIMUM DISPLACEMENT AND ACCELERATION HISTORIES. RESULTS ALSO SHOWED THAT BY ADDING THE YIELDING DAMPERS, THE NATURAL PERIOD OF THE SYSTEM IS INCREASED AND THE MAXIMUM BASE SHEAR IS REDUCED UP TO 70 PERCENT.
