Beam-to-column connections in reinforced concrete moment-resisting frame structures are vulnerable to high horizontal shear stresses during seismic events. Ensuring integrity, shear strength, and ductility in these critical regions often involves complex detailing and reinforcement congestion. To overcome this problem, fiber reinforced cementitious composites (FRCC) have been proposed as an alternative material for beam-to-column connections. However, there is a lack of a comprehensive model for FRCC joint behavior. In this study, a shear strength prediction equation and a parametric shear stress-strain model are developed for FRCC beam-to-column connections, based on an extensive database of experimental data. The proposed models are validated against experimental data, existing equations, and code estimations, demonstrating their accuracy and applicability. This research enhances understanding and provides practical guidance for designing efficient and resilient FRCC beam-to-column connections, paving the way for safer and more sustainable structures.
