Semi-rigid steel frame beam-column joint based on buckling-restrained angle steel
The invention discloses a semi-rigid steel frame beam-column joint based on buckling-restrained angle steel, and compared with common angle steel and T plate connecting joints, the joint has the advantages of simple structure, clear stress, convenience in design and the like. The device comprises a column, a beam, dog-bone-shaped angle steel, shear plates, buckling-restrained angle steel, cushion blocks, connecting plates, stiffening ribs and bolts, full-bolt connection is adopted, mounting and dismounting are convenient, the four-dog-bone-shaped angle steel is attached to the periphery of a beam web, the influence on a floor is small, the shear plates are connected with the beam web through round holes and slotted holes, rotation in a plane is allowed, and the buckling-restrained angle steel is not prone to deformation. At the moment, the shear plate bears shear force, the dog-bone-shaped angle steel bears bending moment, when an earthquake occurs, plastic deformation of the joint is concentrated on a weakening section of the dog-bone-shaped angle steel, the beam and the column are in an elastic state, and only the damaged angle steel needs to be replaced after the earthquake ends.
本发明公开了一种基于防屈曲角钢的半刚性钢框架梁柱节点，该节点与普通角钢、T板连接节点相比，具有构造简单、受力清晰、便于设计等优点。本发明包括柱、梁、狗骨型角钢、剪力板、防屈曲角钢、垫块、连接板、加劲肋和螺栓，采用全螺栓连接，便于安装和拆卸，四狗骨型角钢贴在梁腹板周围布置，对楼板的影响较小，剪力板采用圆孔和槽孔与梁腹板连接，允许平面内转动，此时剪力板承担剪力，狗骨型角钢承担弯矩，地震发生时，节点的塑性变形集中于狗骨型角钢的削弱段，梁和柱处于弹性状态，地震结束后，仅需更换受损的角钢。
