Low-prestress slope friction energy dissipation self-resetting concrete beam-column joint device
The invention discloses a low-prestress slope friction energy dissipation self-resetting concrete beam-column joint device which comprises a precast concrete column, a precast concrete beam located on one side of the precast concrete column and a slope friction energy dissipation device connecting the precast concrete column and the precast concrete beam into a whole. The slope friction energy dissipater comprises a middle slope steel plate with a slope, an outer slope steel plate with a slope and an inner plane steel plate pre-buried in the precast concrete beam; according to the invention, the rigidity is continuously increased along with the increase of earthquake intensity, so that not only can the anti-seismic requirements of the structure under small earthquake intensity and medium earthquake intensity be met, but also the energy under the action of large earthquake can be better consumed, and the interlayer angular displacement, the floor acceleration and the like of the structure are obviously reduced; the method has the advantages of small post-earthquake residual deformation, light structural damage and the like, and meanwhile, obvious plastic deformation of main structural members such as precast concrete beam columns and the like is avoided.
本发明公开了一种低预应力坡面摩擦耗能自复位混凝土梁柱节点装置，包括预制混凝土柱、位于预制混凝土柱一侧的预制混凝土梁、将预制混凝土柱和预制混凝土梁连接为一体的坡面摩擦耗能器，坡面摩擦耗能器包括带坡面的中坡面钢板、带坡面的外坡面钢板、预埋在预制混凝土梁中的内平面钢板；本发明随着地震强度的增加，刚度也不断增大，不仅可以满足结构在小震、中震强度下的抗震需求，还可以更好地消耗大震作用下的能量，使结构的层间角位移和楼层加速度等显著减小；本发明具有震后残余变形小，结构损伤轻等优点，同时避免预制混凝土梁柱等主体结构构件出现明显的塑性变形。
