Fiber Reinforced Concrete Joints for Precast Construction in Seismic Areas

Six beam type specimens, each consisting of 2 precast reinforced concrete parts joined together by a cast-in-place fiber reinforced concrete connector, were tested by under cyclic third-point loading. The tests were part of a comprehensive study aimed at developing a strong, ductile, and energy-dissipating connection for preacast concrete construction in seismic zones. It was observed that the cast-in-place joints, despite experiencing a localized failure due to the presence of a single major crack, exhibited higher levels of ductility and energy dissipation compared to cast-in-place conventional concrete joints.
