Construction device and method for self-resetting fabricated RCS beam-column joint
The invention belongs to the technical field of building materials, and discloses a construction device and method for a self-resetting assembly type RCS beam-column joint. The beams are steel beams; the RCS node is assembled through a lug plate and a pin shaft; the multi-section weakening plate energy dissipation assembly is connected with the steel beam and the energy dissipation piece embedded connecting piece through bolts. Prestressed steel strands are symmetrically arranged at the web of the steel beam; according to the joint, the ductility and energy dissipation capacity of the joint under the reciprocating load are improved by utilizing the characteristics of low yield point and high ductility of the multiple sections of weakening plates and the characteristic of restrained buckling, so that after the structure is damaged by earthquake, the use function of the structure can be quickly recovered only by replacing the energy dissipation assembly of the multiple sections of weakening plates, and the construction cost is reduced. And meanwhile, the self-resetting function of the beam column joint is achieved by arranging the post-tensioned prestressed tendons, the problems that a traditional RCS beam column joint is poor in energy dissipation performance at the beam column component splicing position and insufficient in post-earthquake repairability are solved, and the purposes of energy dissipation in the earthquake and non-destructive repairing after the earthquake can be achieved.
本发明属于建筑材料技术领域，且公开了一种自复位装配式RCS梁柱节点的施工装置及方法，其中，柱为预制混凝土柱；梁为钢梁；RCS节点通过耳板和销轴装配；多段削弱板耗能组件与钢梁、耗能件预埋连接件通过螺栓连接；在钢梁腹板处对称布置预应力钢绞线；本发明节点通过利用多段削弱板低屈服点高延性的特性及约束屈曲的特点来改善节点在往复荷载下的延性及耗能能力，因此，在结构受到震损后，只需要更换多段削弱板耗能组件就可快速恢复结构的使用功能，同时通过设置后张预应力筋实现梁柱节点自复位功能，解决了传统RCS梁柱节点在梁柱构件拼接部位耗能性能差以及震后可修复性不足的问题，可实现震中耗散能量且震后无损修复的目标。
