To make this comparison, the differences between clamp joint and bolted joint were evaluated using a novel methodology based on the analysis of the structure\u2019s natural frequencies from accelerometers. To perform this comparison, several laboratory tests were carried out on a frame made by clamped joints and the same frame made by bolted joints, using a set of tests on a medium-scale shake table for this purpose.
