Abstract

Abstract: Simplifying the configuration, enhancing the energy dissipation capacity and achieving the adjustable performance are critical challenges in development of dry-connected beam-to-column joint. To address these, a dry-connected rotational friction dissipative beam-to-column joint (DRFDBJ) for precast concrete (PC) frame structures is developed with simple detail and adjustable performance, as well as desirable deformation capacity and energy dissipation capacity. Three solutions concerning the details and assembly sequences are recommended to ensure the expected performance. To validate the performance of the DRFDBJ and the effectiveness of the three solutions, full-scale experimental and numerical investigations were conducted. The results indicated that the desirable seismic performance of the DRFDBJ, including the damage mechanism, load-bearing capability, deformation capacity and energy dissipation capacity, were validated. The adjustable performance of the DRFDBJ was successfully achieved through accurate control of the corresponding yield load. The proposed three solutions were verified to be critical for achieving the target performance of the DRFDBJ. The research outcome can provide a valuable reference for the development of dry-connected beam-to-column joints for PC frame structures. Highlights: A novel dry-connected beam-to-column joint (DRFDBJ) is developed. DRFDBJ features simple details, adjustable and desirable performance. Measures concerning the details and assembly sequences are recommended. Full-scale experimental and numerical investigations are conducted. Performance of DRFDBJ and effectiveness of the measures are validated.
