Anti-buckling restraint steel connecting beam
The invention provides an anti-buckling restraint steel connecting beam which comprises an H-shaped steel connecting beam and a plurality of anti-buckling restraint components. The H-shaped steel connecting beam comprises an upper flange, a lower flange and a web plate, the plurality of anti-bucking restraint components are symmetrically arranged on the two sides of the web plate and arranged at intervals along the length direction of the H-shaped steel connecting beam, the anti-buckling restraint components only are connected with the flanges of the steel connecting beam, and the problem thatthe welding position of a reinforcing rib and a web plate of a traditional steel connecting beam is likely to tear is avoided. The anti-buckling restraint components limit plane external deformationof the web plate of the steel connecting beam and provide stable buckling restraint to enable the web plate to be stressed in the plane approximately, and the ductility and energy dissipating capacityof the steel connecting beam under the earthquake effect are further improved.
发明提供一种防屈曲约束钢连梁。该钢连梁包括H型钢连梁和若干防屈曲约束部件。所述H型钢连梁包括上翼缘、下翼缘和腹板。所述腹板两侧对称布置有若干防屈曲约束部件。所述防屈曲约束部件沿H型钢连梁长度方向间隔布置。防屈曲约束部件只和钢连梁翼缘连接，避免了传统钢连梁存在的加劲肋和腹板焊接处容易发生撕裂问题。防屈曲约束部件限制钢连梁腹板的平面外变形，提供稳定的屈曲抑制，使腹板近似平面内受力，进一步提高了钢连梁在地震下作用下的延性和耗能能力。
