“…These parameters are schematized in Figure 5. Eurocode 3 [29] implemented a component method to estimate the S j,ini of TSACs. In this method, the connection behavior is simulated by a series of different components, each representative of an elastic spring with a specific stiffness and strength.…”

“…Instead, it is possible to represent each component contribution, along with complex interactions among the connection's components, by using detailed finite element models. A detailed finite element approach has high accuracy in simulating the complex M-ϕ curve of connections [29][30][31][32]. Nevertheless, this method is computationally intensive and time-consuming.…”

Hybrid Krill Herd-ANN Model for Prediction Strength and Stiffness of Bolted Connections

The behavior of beam-to-column connections significantly influences the stability, strength, and stiffness of steel structures. This is particularly important in extreme non-elastic responses, i.e., earthquakes, and sudden column removal, as the fluctuation in strength and stiffness affects both supply and demand. Accordingly, it is essential to accurately estimate the strength and stiffness of connections in the analysis of and design procedures for steel structures. Beginning with the state-of-the-art, the capacity of three available component-based mechanical models to estimate the complex mechanical properties of top- and seat-angle connections with double-web angles (TSACWs), with variable parameters, were investigated. Subsequently, a novel hybrid krill herd algorithm-artificial neural network (KHA-ANN) model was proposed to acquire an informational model from the available experimental dataset. Using several statistical metrics, including the corresponding coefficient of variation (CoV), correlation coefficient (R), and the correlation coefficient provided by the Taylor diagram, this study revealed that the krill herd-ANN model achieved the most reliable predictive accuracy for the strength and stiffness of top- and seat-angle connections with double web angles.

“…Additionally, the highest bolt grade (i.e., 12.9) has a positive effect on final joint performance. Extensive studies have also been carried out on traditional bolted end plate joints [3][4][5][6] and design methods in different codes, to provide practical design procedures that guarantee resistances and ductility [7][8]. Wang et al conducted a pseudostatic test on three CFST linking column high-strength bolted end plate joint specimens.…”

A replaceable prefabricated Concrete-filled Steel Tubular (CFST) frame structure is proposed in this paper. The structure has excellent advantages in its construction technology, mechanical behaviour, material application, and post-earthquake recovery and is a green structural system. To explore the seismic performance of the structure, ABAQUS is used to study the influence of different variables on the seismic performance of the node. The hysteretic curve, skeleton curve, stiffness degradation, displacement ductility, and energy dissipation capacity of the node were analysed. The results show that the ductility of this node is basically in a range of 2.02 -5.75, which is generally higher than 3.0 and has optimal deformation. Furthermore, this node's equivalent viscous damping coefficient is higher than 0.35. In addition, increasing the bolt preload can significantly improve the energy dissipation capacity of the structure in a particular range, and an excessive bolt preload has little effect. Moreover, the high-strength concrete can effectively improve the energy dissipation capacity of the structure. As the axial compression ratio increases, the equivalent viscous damping coefficient has an obvious upward trend. Finally, the stress mechanism of this node was comprehensively analysed according to the theory of oblique bars, the unified theory of concrete-filled steel tubes, and the Kupfer-Gerstle yield criterion, considering the influence of steel tubes on the core concrete.
