Assembly type prestressed self-resetting frame beam column replaceable energy dissipation joint
The invention discloses an assembly type prestressed self-resetting frame beam column replaceable energy dissipation joint which comprises a joint core area connecting device, a short steel beam connecting piece, an RC frame beam connecting piece, a replaceable energy dissipation device, a self-resetting device, a pin shaft and a friction base plate. The joint core area connecting device comprises a partition plate, a hoop and a short steel beam. The short steel beam connecting piece comprises a fixing plate, an anchoring plate and an outer friction lug plate; the RC frame beam connecting piece comprises an inner friction lug plate, an RC frame beam connecting end plate and embedded H-shaped steel; the hoop is connected with the fixing plate through the short steel beam, and the outer friction lug plate, the inner friction lug plate and the friction base plate are connected to form a friction energy dissipation device. The pin shaft is in running fit with the friction energy consumption device; the anchoring plate and the RC frame beam connecting end plate are connected through a replaceable energy consumption device; the RC frame beam connecting end plates are connected with the beam longitudinal bars. Two energy consumption devices are ingeniously designed, and the defect that the energy consumption level of the structure can only be in the low level after a single-form energy consumption component loses efficacy is overcome.
本发明公开了一种装配式预应力自复位框架梁柱可更换耗能节点，包括节点核心区连接装置、短钢梁连接件、RC框架梁连接件、可更换耗能装置、自复位装置、销轴、摩擦垫板；节点核心区连接装置包括隔板、抱箍、短钢梁；短钢梁连接件包括固定板、锚固板、外磨擦耳板；RC框架梁连接件包括内磨擦耳板、RC框架梁连接端板、嵌入H型钢；抱箍通过短钢梁与固定板连接，外磨擦耳板、内磨擦耳板、摩擦垫板连接形成摩擦耗能装置；销轴与摩擦耗能装置转动配合；锚固板、RC框架梁连接端板通过可更换耗能装置连接；RC框架梁连接端板与梁纵筋连接。本发明通过巧妙地设计两种耗能装置，避免了单一形式的耗能构件失效后结构的耗能水平仅能处于较低水准的不足。
