Self-resetting corner damper at joint of wooden beam column
The invention discloses a self-resetting corner damper at the joint of a wooden beam column, and relates to the technical field of structural displacement dampers. Comprising a wood cylinder, a wood rectangular beam, a column hoop, a beam hoop, a corner support and a spring damper, and the wood cylinder and the wood rectangular beam are connected through mutually embedded mortise and tenon joints. The corner support and the beam-column joint corner displacement are coordinated and synchronous, and the spring damper absorbs energy generated by beam-column joint bending moment after the corner displacement is generated when the beam generates downward deflection. According to the device, the corner support and the spring damper which are connected through the beam column hoop are arranged, work done by beam column joint bending moment in the corner displacement direction is converted into elastic potential energy in the damper, the plastic deformation capacity of a beam under the large load effect after a joint material is yielded is improved, the capacity that a large corner is achieved, and large deformation is not damaged is achieved; and after the load is removed, the joint corner is also reset, a certain self-resetting capacity is achieved, and the component has high stability when facing the low-cycle reciprocating load.
本发明公开了一种木质梁柱结合处的自复位转角阻尼器，涉及结构位移阻尼器技术领域。包括：木圆柱、木矩形梁、柱套箍、梁套箍、转角支架、弹簧阻尼器，木圆柱与木矩形梁之间采用相互嵌合的榫卯连接。转角支架与梁柱节点转角位移协调同步，弹簧阻尼器在梁产生向下挠度时，吸收梁柱节点弯矩在转角位移发生后产生的能量。本装置通过设置梁柱套箍连接的转角支架及弹簧阻尼器，将梁柱节点弯矩在转角位移方向上所做的功转化为阻尼器中的弹性势能，提高了梁在大荷载作用下节点材料进入屈服后的塑性变形能力，具备大转角、大变形不破坏的能力，且荷载撤除后节点转角也重新归零，具备一定的自复位能力，面对低周往复荷载时构件具有较强的稳定性。
