Truss type replaceable energy dissipation coupling beam with buckling restrained braces
The invention discloses a truss type replaceable energy dissipation coupling beam with buckling restrained braces. The truss type replaceable energy dissipation coupling beam comprises a truss type coupling beam body, coupling beam end components and a pre-embedded connecting steel plate; the truss type coupling beam body comprises a square steel tube upper chord member, a square steel tube lower chord member, hinged connecting pieces and the buckling restrained braces; the hinge connecting pieces are fixedly connected to the two ends of the square steel tube upper chord and the square steel tube lower chord, and the two buckling restrained braces are connected with the hinge connecting pieces through pins, so that the two buckling restrained braces form diagonal web members in the truss type coupling beam, are in a cross shape and are not in contact; and the pre-embedded connecting steel plate is arranged in a wall body, the coupling beam end components are welded at the two ends of the square steel tube upper chord member and the square steel tube lower chord member, and the truss type coupling beam body and the pre-embedded connecting steel plate can be hinged through the coupling beam end components. According to the truss type replaceable energy dissipation coupling beam, shear deformation of a common coupling beam is converted into axial deformation of the buckling restrained braces, so that the buckling restrained braces serve as a first anti-seismic defensive line, and after the buckling restrained braces are damaged, the square steel tube upper chord and the square steel tube lower chord form a new coupling beam serving as a second defensive line.
本发明公开一种带屈曲约束支撑的桁架型可更换消能连梁，包括桁架型连梁、连梁端部构件和预埋连接钢板；所述桁架型连梁包含方钢管上弦杆、方钢管下弦杆、铰接连接件和屈曲约束支撑；铰接连接件固接于方钢管上弦杆和下弦杆的两端，两个屈曲约束支撑通过销钉与铰接连接件相连，使之成为桁架型连梁中的斜腹杆，呈十字交叉形且无接触。预埋连接钢板设置于墙体内，连梁端部构件焊接于方钢管上弦杆和方钢管下弦杆的两端，桁架型连梁和预埋连接钢板可通过连梁端部构件铰接。本发明将一般连梁的剪切变形转化为屈曲约束支撑的轴向变形，使得屈曲约束支撑为第一道抗震防线，在屈曲约束支撑破坏后，方钢管上弦杆与方钢管下弦杆形成新的连梁，为第二道防线。
