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