Experimental Analysis of Structural Damping for Bolted and Welded Splice Connection Joint for Ipe-80 Steel Profile

Abstract

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

Experimental and numerical study of structural damping in a beam with bolted splice connection

“…Our research follows a macro scale approach and the secondary phenomena arising in bolted connections that can influence structural response. Some preliminary findings are already discussed in previous papers [73,74]. The main contributions of the presented research are the comprehensive calibration, verification, and validation of a numerical model of one BBSC.…”
