| Summary: | This article presents experimental and analytical investigations of hybrid-steel concrete connections.
In the experimental study, four full-scale specimens including one cast-in-place and three
precast specimens were tested under cyclic load reversals. The performance of the specimens in
terms of energy dissipating capacity, cracking patterns, and variation of strains along the main
reinforcement is described. However, due to the inherent complexity of beam-column joints and the
unique features of the tested specimens, the experimental investigation was not sufficient enough to
fully understand the influence of several parameters. Therefore, an analytical investigation based
on the FE models using DIANA software is presented. Validation of the FE models against the
experimental results has shown a good agreement. The critical parameters influencing the joint’s
behavior such as the continuation of beam bottom reinforcement, column axial load, the size and
embedded length of the angle sections are varied, and their effects including possible implications
on code specifications are discussed. |
