Seismic behavior of a friction‑type artifcial plastic hinge for the precast beam–column connection

Popis výsledku v původním jazyce

This paper proposed a replaceable friction-type artifcial plastic hinge (FAPH) to connect the prefabricated concrete members,ncharacterized by direct load transmission and streamlined confguration. The FAPH device replaced the beam-end plasticnhinge region in the precast structures, which could protect the concrete joint core area and other concrete components. Thenexperiment of a precast beam–column connection with FAPH and a cast-in-situ beam–column connection was carried out.nThe experimental results showed that the FAPH connection had better hysteresis performances with higher bearing capacity,nenergy dissipation, and ductility than the cast-in-situ concrete connection. Moreover, the fnite element model was calibratednand employed to perform parametric analyses, including the axial load ratio, the friction factor, the bolt preload, and theninitial clearance. The FE analysis results showed that the FAPH connection would have a more attenuation of the frictionnforce under the higher axial load ratio. Besides, the seismic performance of FAPH can be efectively improved with thenincrease of the friction factor and the bolt preload, and the FAPH connection exhibited a stable performance with variousninitial clearances. Based on the parametric analysis results, the formulas for the yield and peak bending moment capacitynfor the FAPH device were proposed.
