Abstract

This experimental study investigated the behavior of beam-column connections with beams weak in shear. The experiment involved connections of varying sizes: full, two-thirds, and one-third size, subjected to loading types 1 and 2. Following testing, different rehabilitation strategies were employed based on the observed degree of damage. The rehabilitated specimens were then re-tested using the same loading sequence as the control specimens. Data collected during testing was utilized for post-processing to evaluate various parameters related to the seismic capacity of the connections. The performance of the rehabilitated specimens was examined and compared with that of the original, deficient control specimens. Bi-logarithmic plots were utilized to investigate the potential impact of size on ultimate strength, and correlations were established between specimen sizes, cumulative energy dissipation per unit volume of the D-region, and stresses. This comprehensive analysis sheds light on the behavior of beam-column connections with weak shear and provides insights into effective rehabilitation strategies.
