“…They also proposed some recommendations for the weld access hole's size beneath the butt joint between the beam flange and the horizontal continuity plate. It should be noted that many studies on RBS connections provided in the literature have been based on wide-flange columns (Engelhardt et al (1998) [7], (2000) [8]; Gilton et al (2000) [9]; Iwankiw (2004) [10]; Kim et al (2016) [11]), and attention to the seismic performance of this connection in box-columns has been negligible.…”

This paper presents a review on the seismic performance of steel beam connected to box column. The strength and deformation capacity of structural elements are influenced by their cumulative damages received through load cycles. Several researchers have been studying the behaviour of seismic performance of steel beam connected to box column filled with concrete but due to its complex behaviour yet it is not completely understood, where the international design standards and specifications are limited to the Hshaped columns. The rotational capacity and dissipated energy of the welded and bolted connections are discussed. The local responses for stress and strain in the vicinity of welded and bolted joints are also investigated.

“…It is then a matter of concern that a structure, if designed according to the present seismic code, may be unsafe if its connections or joints using high-strength steels are exposed to large plastic deformation under major earthquakes. With regard to bolted beam-to-column connections, which are advantageous for rapid on-site construction, there have been a few studies to evaluate the static and seismic behaviour of bolted high-strength steel extended and flush end-plate connections [3][4][5][6][7][8][9][10]. However, the existing research on bolted connections using high-strength steels of 690MPa or higher is still scarce, and there is little information on whether how much ductility and energy dissipation those bolted connections can develop.…”

Cyclic loading tests on 690MPa high‐strength steel bolted extended end‐plate connections were conducted to quantify their plastic resistance and plastic rotational capacity under seismic loading conditions. It was found that current formulae in Eurocode 3 Part 1‐8 still arrived at good predictions on plastic resistance of those connections. It was demonstrated that given the bolt grade and diameter, the end plate with an intermediate thickness led to the largest plastic rotation. Such an intermediate, or optimal, end‐plate thickness indicates that the upper limit of the end‐plate thickness, which is now specified in Eurocode 3 Part 1‐8 to ensure a sufficient rotation capacity, should be levered up by about 40% for 690MPa high‐strength steels in seismic design. In such a manner, the maximum plastic rotation of the high‐strength steel end plate was around 0.02rad. In addition, the high‐strength steel shear panel was able to develop a plastic rotation of at least 0.035rad, thus qualified as high‐ductility class (DCH) in Eurocode 8. The weak shear panel contributed for more than 70% of the total plastic rotation capability.

“…These elements must be designed to withstand seismic loading due to earthquakes [17]. Consequently, some scholars focused on investigating T shaped steel connections with solid beam web such as Kim et al [18] who studied the seismic performance of these connections experimentally and Calado [19] who suggested using an analytical model to investigate their behavior. It became clear that with no web opening the plastic section formed close to column face instead of the rest of the beam span.…”

In the last decades, steel beams with web opening were used extensively as useful structural and architectural elements due to their many advantages. In this research, steel beams with web opening subjected to static loading were modelled using the multi-purpose finite element software ANSYS and the finite element results were compared with previous research. Then, steel beams with a single web opening subjected to fatigue loading were investigated numerically. The effect of changing the location of web opening on the fatigue assessment of H section steel beams with web opening was studied taking normal stress into account. It was clear that, normal stress fatigue life of the steel beams was affected significantly by changing web opening location along the beam span when compared to a beam with solid web while the beam span, opening size and steel section were kept constant. The most convenient location of web opening along the beam span was found to be at mid span.
