“…di Sarno et al [21] conducted a numerical study on the case studies in Amatrice, Central Italy, which were moment resisting frame buildings and suggested possible improvements. Cyclic performance of post-Northridge welded connections was assessed by Yilmaz and Bekiroglu [22] in ANSYS software. Reduced Beam Section (RBS), Welded Unreinforced Flange -Welded Web (WUF-W), and Welded Flange Plate (WFP) connections were evaluated, and it was concluded that high stiffness and high safety belong to WFP and RBS connections, respectively.…”

In the Northridge and Kobe earthquakes, brittle failure of the welded beam-to-column connections was observed in steel structures. So, bolted connections were considered as an alternative to these kinds of connections. Extended end-plate beam-to-column con-nection is one of the most commonly used connections in steel structure. In this article, the behavior of the sloped extended end-plate beam-to-column connections is studied. Finite element method was used to investigate the behavior of the connection by ABAQUS software. The main aim of the study was to investigate the cyclic behavior of the four beam-to-column connections with beam angles of 0, 10, 15, and 20 degrees with respect to horizon. Also, the behavior of the mentioned connections was compared with extended end-plate connections with perpendicular angle. Results showed that the ductility and moment-resisting capacity of the sloped extended end-plate beam-to-column connections decrease by increasing beam angle, but rotational and moment-resisting capacities of the models satisfy the limitation of the design codes such as 0.04 drift limit for bearing capacity before failure.

“…Despite the application of the RBS method to the beam flanges, the fracture still occurs in close proximity of the connection in some instances [14]. In 2018, Yilmaz and Bekiroglu [15] conducted research regarding improved connections, consisting of steel connections with Cover Plates and RBS. The panel zone performance and damping performance of connections with Cover Plates are inadequate.…”

This paper presents the result of four welded connections under cyclic loading using finite element analysis, those are: Conventional Connection (C-Con), Cover Plates Connection (CP-Con), Reduced Beam Section Connection (RBS-Con), and RBS Connection using Cover Plates (RBSCP-Con) using the same material properties, including dimension of the profile and its span. Previous research indicates that, even though the fact that the initial seismic yield must be located far from the column’s face, it still occurs on the majority of RBS connections on occasion. By adding a cover plate to the top and bottom flanges of the beam, the research can provide a seismic design improvement for RBS connections. The analysis results observed that cyclic performance of RBSCP-Con was much superior to the other connections in terms of plastic hinges location, panel zone’s performance, and failure modes. However, CP-con has the maximum value of energy dissipation, which correlates with its hysteresis curves. Furthermore, all of the four types of connections already satisfy SMF category requirements in accordance with AISC 341-16.

Load transmission from one element to another is achieved using steel connections, making them an integral part of any structural design. This article examines the differences between the American Codes (AISC) and Eurocode 3 for the design and analysis of steel connections. Moment connections' stiffness, strength, and ductility as expressed in both codes are the core focus of this research. Each tactic's advantages and disadvantages have been detailed, and the effect of seismic load on steel connection design has been investigated. The feasibility of using techniques like haunches and stiffeners to enhance connection design is also explored. The study focuses on moment connections and how they fare under different loads and conditions like stiffness, strength, and ductility. Additionally, the effect of seismic loading on the development of steel connections is analyzed. Finally, the significance of testing and documentation to guarantee the safety and dependability of steel connections has been evaluated. This research can help engineers select a suitable code and connection typology for their projects for improved performance of the overall structural behaviour.
