The invention discloses a reinforcement structure and reinforcement method for a beam column joint. The reinforcement structure comprises CFRP plate strips and memory alloy wires. The beam column joint comprises a concrete column and concrete beams distributed on the left side and the right side of the concrete column. Through holes penetrating the front portions and the rear portions of the concrete beams are correspondingly formed in the ends, close to the core region of the beam column joint, of the two concrete beams. The two ends of each memory alloy wire correspondingly penetrate the twocorresponding through holes and are fixedly connected through a clamping head, and the memory alloy wires are wound around the periphery of the concrete column. Gaps between the memory alloy wires and the inner walls of the corresponding through holes are filled with glass cement. Strip-shaped grooves longitudinally distributed along the concrete beams and provided with downward groove openings are correspondingly formed in the beam bottoms of the two concrete beams. The CFRP plate strips are horizontally arranged in the strip-shaped grooves. The portions between the CFRP plate strips and theinner walls of the strip-shaped grooves are filled with epoxy resin adhesive. By the adoption of the reinforcement method, the built-in CPRP plate strips and the memory alloy wires wound around the concrete column are used in a combined manner, the anti-seismic performance of the beam column joint is effectively improved.
本发明公开一种梁柱节点的加固结构和加固方法，所述加固结构包括CFRP板条和记忆合金丝，梁柱节点包括混凝土柱以及分布在所述混凝土柱左右两侧的混凝土梁，两个所述混凝土梁靠近所述梁柱节点的核心区的一端分别设有前后贯穿其的通孔，记忆合金丝的两端分别穿过两个通孔且通过夹头连接固定，并缠绕在混凝土柱的外周，记忆合金丝与对应通孔内壁之间的间隙内填充有玻璃胶，两个所述混凝土梁的梁底分别设有沿其纵向分布且槽口朝下的条形槽，CFRP板条水平设置在条形槽内，CFRP板条与条形槽的内壁之间填充有环氧树脂胶。本发明公开的加固方法将内嵌的CFRP板条和将缠绕在混凝土柱上的记忆合金丝复合使用，有效地提高了梁柱节点的抗震性能。
