Self-resetting friction energy dissipation steel frame joint based on shape memory alloy
The invention relates to a self-resetting friction energy dissipation steel frame joint based on shape memory alloy. A gap is reserved between an H-shaped steel column and an H-shaped steel beam; steel sleeve plates are welded to the two sides of a beam-column joint area formed by the H-shaped steel column and the H-shaped steel beam correspondingly, steel sleeve plate hole grooves are formed in the middle portions, close to the side of the H-shaped steel column, of the steel sleeve plates, and the steel sleeve plate hole grooves are oval; a beam circular hole is formed in the middle of an H-shaped steel beam web, close to the side of the H-shaped steel column, of the H-shaped steel beam, a third shape memory alloy rib hole channel is formed in an upper flange of the H-shaped steel beam, and a fourth shape memory alloy rib hole channel is formed in a lower flange of the H-shaped steel beam; reinforcing plates are welded to the two sides of the beam circular hole, the height of the reinforcing plates is equal to that of the web of the H-shaped steel beam, and reinforcing plate round holes are formed in the reinforcing plates and correspond to the beam circular hole; and according tothe joint, the problems of residual deformation, brittle failure, insufficient energy consumption and the like of the steel frame under the earthquake action are effectively solved.
本发明涉及一种基于形状记忆合金的自复位摩擦耗能钢框架节点，H型钢柱和H型钢梁之间留有空隙；H型钢柱和H型钢梁形成的梁柱节点区的两侧均焊接有钢套板，钢套板靠近H型钢柱侧的中间部位设有钢套板孔槽，钢套板孔槽为椭圆形；H型钢梁靠近H型钢柱侧的H型钢梁腹板中间部位设有梁圆孔，并在H型钢梁上翼缘上设有第三形状记忆合金筋孔道，H型钢梁下翼缘上设有第四形状记忆合金筋孔道；梁圆孔两侧均焊接有加强板，加强板与H型钢梁的腹板等高，加强板上设有加强板圆孔，加强板圆孔与梁圆孔对应；通过本发明，有效地解决了钢框架在地震作用下的残余变形、脆性破坏及耗能不足等问题。
