PREDICTION OF THE TENSILE STRAIN OF LAMINATED RUBBER BEARINGS AND THE BENDING MOMENT OF BEAMS DUE TO SUPERIMPOSED HORIZONTAL AND VERTICAL RESPONSES USING CONSTANT ENERGY RULE

Abstract

Past study had proposed a design method for base isolated structure considering tensile strain. Therefore, this paper proposes a method to predict the tensile strain of laminated rubber bearings and the moment of beams due to superimposed horizontal and vertical responses using constant energy rule. This proposed method considers that the tensile modulus of rubber bearing is lower than its compression modulus.
