Shear reinforcement is one of the common measures used to strengthen slab–column connections. It can make joint’s load capacity increase. However, when connection subjected an unbalanced bending moment, reduction effect shear on moment worth investigating. Nonlinear finite element analysis was performed reinforced concrete slabs with for various moment-to-shear (M/V) ratios. The effects number ...

Progressive collapse of reinforced concrete flat plate systems can be significantly influenced by the post-punching performance their slab–column joints under large deformations. This work presents a series static tests on four joint specimens with slab in-plane restraint. The effects different punching directions (upward and downward) embedded beams were studied. test results reveal that load-...

Abstract Evaluation of shear capacity is crucial for existing concrete buildings and bridges. Shear failure can cause an abrupt brittle loss load‐carrying capacity, leading to load redistribution progressive collapse. An internationally research scietific discourse actively ongoing on the best prediction model shear, torsion, punching with no clear consensus. A machine learning‐based strength s...
