BEAM-COLUMN JOINT OF PREFABRICATED SELF-CENTERING RC FRAME BASED ON SMA MATERIAL
Provided is a beam-column joint of a prefabricated self-centering RC (Reinforced Concrete) frame based on an SMA (Shape Memory Alloy) material, including an RC precast column, an RC precast beam, and self-centering energy dissipation dampers arranged, and a friction energy dissipation damper. The self-centering energy dissipation damper includes an SMA kernel, an upper restraint cover plate, a lower restraint cover plate, a column-end connection reinforcing plate and a beam-end connection reinforcing plate, and a set energy dissipation gap is reserved between the SMA kernel and the upper restraint cover plate. The friction energy dissipation damper includes an in-column embedded connecting plate and a beam-end embedded connecting plate. The in-column embedded connecting plate and the beam-end embedded connecting plate each are provided with a primary connecting hole and secondary connecting holes, and each of the secondary connecting holes on the beam-end embedded connecting plate is an arc-shaped elongated hole.
