Application of Elastomeric Dampers to Steel Moment Resisting Frames

Abstract

Abstract. In this paper the hysteretic behaviour of elastomeric dampers and their effect on steel moment resisting frames was evaluated. A new constitutive model was proposed, based on the Generalized Maxwell Model (GMM), which was able to capture the characteristics of the dampers under dynamic loading in a range of frequencies and amplitudes. This model was incorporated into the Finite Element (FE) Software OpenSees [1], and was used to validate the dampers behaviour. A simple steel moment resisting frame was modelled, and analytically tested under under strong ground motions, scaled according to Eurocode 8 [2] response spectrum. Both analytical and experimental results show the efficiency and the effectiveness of the elastomeric dampers with regard to structural response.

“…In addition, Kelly and Konstantinidis [3,4] considered the application of pure compression or pure bending to EBs, by considering linear elastic rubbers and infinitesimal strain theory. Experimental studies have been also proposed [5][6][7][8][9][10] in order to develop formulations that represent the interaction between the axial and the horizontal stiffness under shear deformations. Experimental studies on EBs were conducted by Cardone and Gesualdi [11] with the aim to investigate the role of the air temperature demonstrating that it alters considerably the stress levels and the shear stiffness of the elastomer.…”
