【摘要】 通过木结构木销连接榫卯节点模型的拟静力低周反复加载试验,得出了销连接节点的力-位移滞回曲线、骨架曲线、转角,并得到试验后结构的破坏形态。试验结果表明:此种榫卯结构在水平荷载作用下正、反两个方向的骨架曲线差别较大,木销成为此种结构受剪破坏的控制性因素,适当提高销子的强度,可较明显地增加木构架的抵抗水平荷载作用的能力,结构的延性可通过节点销槽的扩孔作用来加以保证,试验结果对此类结构的设计具有参考意义。更多还原

【Abstract】 In the paper,the hysteresis curve,skeleton curve rotation angle and failure pattern of the joint connected by a timber pin were presented,based on the pseudo static test of an mortise and tenon joint model of timber structure. The experimental results indicate that the joint ’s skeleton curves are different in two directions under horizontal load,and the timber pin becomes as a key factor to control this kind of structure. Suitably increasing the strength of the timber pin can obviously improve the timber frame’s ability of resistance to the action of horizontal loading,while the ductility of the structure can be ensure by the spreading function of tenon hole. Finally,the test results would be the reference for design of such structures.更多还原
