“…It has good mechanical properties after solidification [14], but building structures made of concrete are usually solid, which makes the stress inside the structure have a great impact on the structure, especially under the influence of earthquakes. A hollow structure can avoid the effect of internal stresses but will also cause a reduction in the strength of the structure [15].…”

In order to minimize the loss of life and property in an earthquake, the beamcolumn joints of buildings need to have good seismic performance. This paper briefly introduced concrete beam-column joints and used a steel skeleton to strengthen the seismic performance of concrete beam-column joints. The concrete beam-column and reinforced concrete beam-column joints were prepared for experimental analysis. The skeleton curve and energy dissipation capacity of the joints were tested using quasi-static loading experiments. The relative displacement of the column at different heights in the beam-column joints was tested under an eight-degree earthquake simulated by a vibration table. The results showed that the reinforced concrete beam-column joint had higher peak loads and ultimate displacements when the quasi-static loading displacement exceeded the yield displacement; the reinforced concrete beam-column joint had stronger energy dissipation capacity in the face of cyclic loads; the reinforced concrete beam-column joint had smaller relative column displacements in the face of an eight-degree earthquake.

“…In beam-column joint, the headed bars have the advantage of improving a much wider compressive strength in the joint, along with joint confinement, which improves the joint's overall performance. They also have the advantage of transferring a more uniform distribution of compressive stress to the concrete at the headed end [32,33]. The beam-column junction specimens without joint hoop reinforcement experience significant displacement and develop broader cracks.…”

“…The beam-column junction specimens without joint hoop reinforcement experience significant displacement and develop broader cracks. The ultimate load-carrying capacity, energy dissipation, displacement ductility, and joint shear strength all rise with an increase in joint hoop reinforcement [32,33].…”

The performance of structural composites during loading has always been a concern for the designers and construction industry since the reinforced concrete structure was discovered. In this study, lateral load–displacement behavior of beam–column joints wrapped with aramid fiber is evaluated using both experimental and numerical analysis subjected to torsional moment (beam-eccentric loading). Three categories of reinforcement concepts are adopted for the preparation of the beam–column joints, where members are wrapped with aramid fiber at the joints, and others are not fortified with aramid fibers. Prior to testing, the structural composites are cured for maximum 28 days into water. The beam–column joints are subjected to lateral load at a point near the column end of the beam–column connection, and the corresponding deflections are measured until the member fails. Based on the test results, ductility and energy absorption capacity are evaluated. The findings of the numerical investigation of beam–column joint show there is not much variation in the experimental and numerical analysis; it is clearly found that aramid fiber wrapping provided large rigidity in the joint, and it is also prolonged the final failure of the joints. This study shows that in addition to the conventional reinforcement, providing the hanger reinforcement and the diagonal reinforcement improves the rigidity of the beam–column joints during severe loadings, as this study described.
