Abstract

The present work aims to show our practical achievements made in the laboratory of the UBB Resita faculty, where on Warren truss hinged at both ends, we studied the negative impact of loosening a bolt in a truss node that has them on natural frequency. Based on the bolt tightening, the specimen had three different states: healthy state, damage state I, and damage state II.
