摘要：
Traditional glulam frame connected with slotted-in steel plate are prone to damage at the beam and column ends under the action of earthquake, resulting in poor recoverability of structures. A new timber frame (WFCF) assembled by wooden frictional beam-to-column connections (WFC) and column base joint with column-shoes was developed. Reversed cyclic loading tests were conducted on 1 / 2 scaled single-layer single span traditional timber frame (TTF) and WFCF specimens, respectively. The failure mode, hysteretic behavior and energy dissipation capacity of the specimens were studied. The research results showed that both WFCF and TTF were basically intact under small lateral deformation. However, the splitting failure of TTF was observed when the lateral deformation increased, while WFCF was in good condition, indicating that the function of WFCF can be restored after earthquake. Compared with TTF, the WFCF had almost the same bearing capacity and stiffness, but the energy dissipation capacity was significantly improved, and its equivalent viscous damping coefficient was increased by about 100%. The hysteresis model of WFCF was established, and the prediction model of the hysteretic curve was in good agreement with the experimental results. The developed WFCF can be popularized and applied after further research. © 2023 Editorial Office of China Civil Engineering Journal. All rights reserved.
