Experimental analysis of structural damping for bolted and welded splice connection join for IPE-80 steel profile

Abstract

Progress and demands of all types of constructions imposed the need for the development of modern structures that are lightweight, but at the same time have high damping capacity and stiffness. The consequences of these requirements are increased dynamic problems related to vibrations and dissipative processes in structure connection joints. Structural joints are the main reason for the significant reduction of the level of energy dissipation and source of structural damping so therefore they have become a subject of interest to many researchers. The aim of this paper is to present some problems regarding research of structural damping and the importance of study Contact Mechanics to better understand the problem of structural damping.
