Finite Element Modeling of beam column joint of opening bending moment

Más información sobre el libro

The study focuses on the structural integrity of corner joints formed by two flexural members at a 90-degree angle, highlighting the common issue of tensile strength failure in concrete. It identifies the formation of splitting tensile cracks at re-entrant corners, which compromise stability. While previous experimental research has explored the use of fibers in these joints, this investigation aims to fill a gap by validating those results analytically through finite element modeling, comparing fibrous and non-fibrous concrete under opening moments.
