“…Isotropic friction is considered for tangential behavior, and the friction formula uses the penalty function. The friction coefficient between the steel plate and concrete surface is 0.4 [ 29 ]. With this method, the interface contact force is transmitted between the master and slave surfaces according to the penalty stiffness and penetration conditions when contact occurs.…”

“…The penalty function method was adopted to establish the "normal hard contact" relationship for the contact interface and the separation after contact was allowed. Isotropic penalty friction was considered for tangential behavior, and the friction coefficient between the steel plate and concrete surface was 0.4 [22]. The position affected by the contact force was spatially arbitrary rather than a priori using this contact scheme.…”

During strong seismic events, seismic-induced pounding has been observed to cause damage to bridges. Previous studies on seismic-induced bridge pounding responses have generally focused on reinforced concrete bridges. However, the seismic damage between steel and reinforced concrete beams is significantly different, and research on steel beams’ seismic pounding response remains limited. Therefore, this paper adopts the multiscale fine three-dimensional numerical simulation method to study the seismic response of a slab-on-girder steel bridge. The numerical results show that the lower lateral bracing has a significant effect on seismic damage to steel beams. The lower lateral bracing can share about 1/3 of the pounding action and reduce the displacement angle of the steel beam by 40%. Under horizontal two-way seismic action, the lower lateral bracing significantly reduces the stress on the steel beam. In addition, the bracing should have continuous stiffeners to avoid connection failure. Generally, the lower lateral bracing should be considered in the design of the slab-on-girder steel bridge. It significantly improves the lateral seismic performance of the bridge and reduces seismic damage to steel beams.

“…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.…”

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.
