Abstract

This research leads with the analysis of a structural joint. Different arrays of steel sheets were joined using bolts. The structures were built in a metallic box filled with Granitic 0/3 sand. This box was used as a rigid body to transmit impacts and the sand as a medium to interact between the body and the structure. Then, an optical set-up was placed to measure the interaction of the impact along the different arrays. Measurements were made 5 cm before and 5 cm after the bolt. Results were analyzed by performing signal filtering and approaching a mathematical solution revealing that impact interaction can be harmonic or damped oscillations with more than 98% accuracy.
