Beam column friction energy dissipation joint
The invention discloses a beam column friction energy dissipation joint. The beam column friction energy dissipation joint comprises an energy dissipation device, an H-shaped cross beam and an H-shaped stand column, the H-shaped cross beam and the H-shaped stand column are vertically connected, and the cross beam comprises a first beam section, a second beam section and a third beam section; and the energy dissipation device comprises a friction assembly installed on the second beam section and a friction cylinder installed on the third beam section, the friction assembly is arranged in the friction cylinder and is in friction connection with the friction cylinder, and the yield point of the second beam section is lower than the yield points of the first beam section and the third beam section; when small vibration occurs, vibration energy is consumed through friction between the friction cylinder and the friction assembly; when large vibration occurs, the cross beam deforms, and rotating friction energy consumption occurs between the friction assembly and the friction cylinder; and when violent vibration occurs, the second beam section with the low yield point is firstly damaged, the whole structure inclines towards the direction of the second beam section, continuous collapse occurs, refugees can dodge in a targeted mode in the collapse direction of the whole structure, and then the survival rate of the refugees is increased.
本发明公开一种梁柱摩擦耗能节点，包括耗能装置以及垂直连接的H型横梁和H型立柱，横梁包括第一梁段、第二梁段和第三梁段，耗能装置包括安装在第二梁段上的摩擦组件和安装在第三梁段上的摩擦筒，摩擦组件设置在摩擦筒内并与摩擦筒摩擦连接，第二梁段的屈服点低于第一梁段和第三梁段的屈服点；当发生小的振动时，通过摩擦筒与摩擦组件之间的摩擦完成对振动能的消耗；当发生大的振动时，横梁会发生变形，摩擦组件与摩擦筒之间发生转动摩擦耗能；当发生剧烈振动时，低屈服点的第二梁段首先发生破坏，整体结构会朝向第二梁段的方向倾斜发生连续倒塌，使得避难人员对于整体结构的倒塌方向做出针对性的躲避，进而提高避难人员的生存率。
