بررسی تجربی بر روی عملکرد لرزه ای یک قاب چوبی دیوار دو طرفه

Based on the prototype of a timber palace built during the Chinese Song Dynasty with inverted-trapezoid sectioned dovetail (ITSD) mortise–tenon joints, three 1:4 scaled specimens were fabricated and tested subjected to cyclic lateral loadings. Efforts have been made to study the characteristics of the timber frame, such as the failure mode, the hysteretic and envelope curves, the strength and the stiffness degradation, and the energy dissipation. Besides, the influence of P–Δ effect on the analytical results of timber frames was discussed in detail. Furthermore, the moment–rotation relationship for the ITSD mortise–tenon joints was presented and validated.
