A Review Paper on Looseness Detection Methods in Bolted Structures

Webbolted connections are associated with different structural behaviours. In the mechanical model, single-bolt connections are considered as pin joints, while multi-bolt connections are regarded as semi-rigid connec-tions. In FEM modelling, two developed methods, namely 3D model-ling method and simplified modelling method, are usually employed.
