Multifunctional adjustable energy dissipater for reinforcing wood structure beam-column joint
The invention provides a multifunctional adjustable energy dissipater for reinforcing wood structure beam-column joints, which comprises a friction damper, the friction damper comprises a bearing capacity adjusting device, a rigidity adjusting device and an amplification coefficient adjusting device, one end of the bearing capacity adjusting device is rotatably mounted at the joint of the wood structure beam-column joints, and the other end of the rigidity adjusting device is rotatably mounted at the joint of the wood structure beam-column joints; the other end is connected with an amplification coefficient adjusting device through a rigidity adjusting device, and the two ends of the amplification coefficient adjusting device are rotationally connected to a beam and a column of the wood structure beam-column joint respectively. By arranging the bearing capacity adjusting device, the pre-tightening force can be adjusted to determine the bearing capacity range of the friction damper, friction energy dissipation and shock absorption can be carried out only when the bearing capacity of the damper is larger than that of the damper, and therefore key basic principles of minimum interference, reversibility and integrity of a wood structure are not interfered; and a rigidity adjusting device and an amplification coefficient adjusting device are arranged, so that the energy dissipation efficiency of the damper is high, and the rigidity adjusting and supporting and reinforcing functions of the damper are achieved.
本发明提供了一种用于木结构梁柱节点加固的多功能可调节耗能器，包括摩擦阻尼器，摩擦阻尼器包括承载力调节装置、刚度调节装置以及放大系数调节装置，承载力调节装置的一端转动安装于木结构梁柱节点的连接处，另一端通过刚度调节装置连接有放大系数调节装置，放大系数调节装置的两端分别转动连接在木结构梁柱节点的梁、柱上。本发明通过设置承载力调整装置可以调节预紧力来确定摩擦阻尼器的承载力范围，只有当阻尼器受到大于承载力时，才会进行摩擦耗能减震，从而不干扰木结构关键基本原则：最小干扰性、可逆性、完整性；设置刚度调节装置、放大系数调整装置实现阻尼器耗能效率高，并且达到阻尼器的刚度调节以及支撑加固功能。
