“…Then, a sudden propagation of the crack in a brittle fracture mode followed, characterized with a low cycle fatigue collapse. Deng et al [10] performed also a series of laboratory tests to characterize the end plate material in its different microstructural states. Indeed, owing to the filler metal and the uneven temperature distribution, a welded joint is a compound of three different metallurgical regions: the fusion zone, the heat-affected zone (HAZ), and the unaffected base metal.…”

“…Typical bilinear and trilinear models cannot express the degradation of stiffness and strength and nor can they express the pinching phenomenon. However, in a multilinear model, both stiffness and strength degradation and pinching are expressed as functions of damage state variables. Eurocode3 Annex J was the first code to adopt the concept of components to determine the design properties of bolted connections.…”

Summary The behavior of beam‐to‐column connections is significantly complicated because it depends on the material, nonlinear relationship between different members, and contact of connecting elements. Their hysteretic response exhibits highly inelastic characteristics and continuous variation in stiffness, strength, and ductility. Therefore, accurate hysteretic models of bolted connections are essential to accurate seismic assessment and design. Composed (Hybrid) modeling approach is presented to represent the complex hysteretic behavior of I beam‐to‐concrete‐filled‐tube (CFT) column bolted connection. For the purpose in this study, experimental evaluation of I beam‐to‐CFT column connection with bolted end‐plate under cyclic loading is done. It must be mentioned to make the connection easily applicable practically and also prepare the column flanges continuity, a connection with the bolts penetrated into the CFT column are used since using the stiffeners in hollow sections is not easily applicable. In the composed mechanical–informational modeling framework, the conventional mechanical model is complemented by information‐based model components. Finally, moment–rotation curves of composed model have been compared with experimental results. Comparison showed that the composed model has a good agreement with experimental results. A newly designed specimen for validation purpose of the composed modeling was made and experimented. Composed model was well applied to predict the behavior of new connections. The presented results show that the composed model has a good ability to predict of hysteretic behavior.

“…After a series of pseudodynamic tests of increasing amplitude, the structure was subjected to a final cyclic test performed by imposing a history of displacements at the second storey of the structure. • Graph (D) represents the hysteretic behaviour of joint JA2-4 [4]. The specimen has been tested within an experimental campaign carried out at the University of Trento on steel joints.…”
