characterized by direct load transmission and streamlined confguration. The FAPH device replaced the beam-end plastic
hinge region in the precast structures, which could protect the concrete joint core area and other concrete components. The
experiment of a precast beam–column connection with FAPH and a cast-in-situ beam–column connection was carried out.
The experimental results showed that the FAPH connection had better hysteresis performances with higher bearing capacity,
energy dissipation, and ductility than the cast-in-situ concrete connection. Moreover, the fnite element model was calibrated
and employed to perform parametric analyses, including the axial load ratio, the friction factor, the bolt preload, and the
initial clearance. The FE analysis results showed that the FAPH connection would have a more attenuation of the friction
force under the higher axial load ratio. Besides, the seismic performance of FAPH can be efectively improved with the
increase of the friction factor and the bolt preload, and the FAPH connection exhibited a stable performance with various
initial clearances. Based on the parametric analysis results, the formulas for the yield and peak bending moment capacity
for the FAPH device were proposed.Workplace Institute of Theoretical and Applied Mechanics Contact Kulawiecová Kateřina, kulawiecova@itam.cas.cz, Tel.: 225 443 285 Year of Publishing 2023 Electronic address https://doi.org/10.1007/s43452-022-00526-1
