“…However, welding is not the preferred method, especially on-site due to low productivity and the need for skilled workers [20]. In addition, conventional welded connections present difficulties with quality assurance, and connections can be detached under large deformations [21][22][23]. The NoWS system uses bolts to join the members; therefore, it can maintain constant quality regardless of the efficiency of the worker, and its additional advantages are the shorter construction period and lower cost.…”

The effective retrofit strategy of non-seismic designed structures is required to improve the strength and ductility. Jacketing is the most typical method which can enhance seismic resistance capacity, but there are many disadvantages due to its enlarged jacket section. This study developed a non-welded concrete-filled steel tube system (NoWS) which was installed using bolts in the form of tube-type steel-encased beams and columns; the NoWS could increase the capacity of seismic resistance strength and the ductility of members. One reinforced concrete (RC) frame specimen with non-seismic details and one NoWS were manufactured, and cyclic loading tests were conducted until critical failure was observed in the column after reaching maximum load. As experimental results, the specimen retrofitted with NoWS had excellent seismic performance, showing resistance to lateral load, effective stiffnesses, and energy dissipation capacity approximately 2–3 times greater than the results of an RC frame specimen.

“…Bolted joints are widely used in mechanical engineering, civil and building fields, aerospace engineering and complex space structures [4,5]. For instance, bolted joints are preferred in the steel construction field as an alternative to the welded connections due to its flexibility of reassembling and disassembling [6]. In advanced composite structure applications, the reliability and strength property of the bolted connections in joining main structural parts have made it a more preferable type of fastening mechanism compared to the adhesive bonded joints [7,8].…”

Modelling the dynamic characteristics of the bolted joints in a complex assembled structure with a high accuracy is very challenging due to the assumptions and uncertainties in the input data of the FE model. In this paper, the identification of the dynamic characteristics of the bolted joints structure using the CBUSH element connector is proposed. Modal testing and normal modes analysis are conducted on a thin plate assembled structure with bolted joints. In the simulation work, the CBUSH element connector is employed and the stiffness coefficient for six degrees of freedom is computed based on four flexibility formulae. The predicted natural frequencies and their corresponding mode shapes are compared against the results of the experimental work. A good agreement of the FE model is achieved by using the coefficient of stiffness as represented in the Swift flexibility formula. The study justifies that the dynamic characteristics of the bolt joints could be accurately modelled by using the CBUSH element connector. The obtained findings provided an alternative approach to modelling the dynamic characteristics of a thin plate assembled structure with bolted joints.
