Our faculty member, Assoc. Prof. Reşat Atalay Oyguç, as part of a collaborative research group, has published a new article focusing on the seismic behavior of reinforced concrete (RC) frame’s beam–column joints.

Comprehensive shake table tests were carried out on a one-third scale, single-story RC frame representative of typical 1980s construction practices in Türkiye. Seismic input was based on ground motions recorded during the 2023 Kahramanmaraş earthquake.

Experimental results revealed a maximum lateral displacement of 53.1 mm and a damage index of 0.758, indicating near-collapse performance. Observed damage included extensive shear cracking and concrete spalling at beam–column joints, along with pronounced pinching under cyclic loading. The findings underscore the urgent need for targeted seismic retrofitting and provide critical data to support revisions in seismic design codes.
