“…Another important conclusion from the literature is that problems of shear in wide beams can be successfully mitigated by the provision of shear reinforcement [13]. Moreover, the performance of the connections is improved when denser hoops are provided in the vicinity of the joints and when hoops are placed inside the joint [14,15].…”

Beams with width greater than their depth and depth equal to the depth of the slab (concealed wide beams) are widespread in Reinforced Concrete (RC) buildings in Albania. A large number of RC buildings with wide beams were hit by a strong Mw6.4 earthquake on 26 November 2019. The earthquake hit two of the most densely populated areas in Albania and caused widespread damage to these buildings. This paper aims to provide an updated view on the seismic performance of buildings with wide beams in light of the new field data following the 26 November 2019 Albania earthquake. To this end, a thorough literature review including experimental and field observations from past earthquakes is presented and data from field visits in Albania are described. It was found that damage to the joists and wide beams themselves was limited, even when the buildings suffered significant non-structural or structural damage in other elements as a result of the earthquake. A discussion on the behavior of wide beam–column frames based on nonlinear structural analyses and tests from the literature is presented. Furthermore, the implications of the results of the analysis for the seismic performance of RC buildings are discussed and confronted with observations from the 2019 Albania earthquake. Based on the literature review, further experimental research on wide beams with longer and more realistic span lengths is recommended.

“…However, some outliers are present, with yield drift below 1.0%. For instance, specimen IJ-F1 suffered in shear, resulting in low capacity and low ductility [14]. The other outliers are the specimens IWB1, IWB2 and IWB3 tested by [6].…”

“…However, considering the effect of slab on the beam flexural resistance, the additional increase due to a strengthening intervention only on the beam should be carefully evaluated in terms of strength hierarchy. Accounting for this, in [11] an effort was made to optimize the beam's detailing of newly constructed (code-conforming) interior wide beam-column joints in order to obtain a better performance under seismic actions. In [12] an experimental program was carried out to investigate the cyclic behaviour of code-conforming exterior wide beam-column connections depending on the type of column (circular, rectangular) and the type of spandrel beam (shallow or deep).…”

This study is devoted to experimentally investigate the seismic behaviour of reinforced concrete (RC) wide beam–column joints equipped with a steel jacketing seismic strengthening solution. To this end, three identical full-scale specimens have been tested under cyclic loading, one in the as-built condition and two after the application of the strengthening solutions. Details of selected solutions are described in the paper along with the experimental results which confirm how the application of simple and feasible steel interventions can effectively improve the seismic capacity of wide beam–column connections in RC frames, especially in terms of lateral load carrying capacity and energy dissipation.
