RC columns strengthened by steel caging: Cyclic loading tests on beam-column joints with non-ductile details
[EN] Beam-column joints suffer intense damage from seismic events and are the cause of many buildings collapsing. These zones present complex behaviour under cyclic loads, including tensile-compression cycles, which make reinforcement adherence worse and cause severe cracking in concrete. Although c...
