Referring to fig. 1, the present embodiment discloses a novel shear type buckling-free energy dissipation brace, which includes a restraining unit, two symmetrically arranged brace core members 2, and energy dissipation steel plates 3.
The restraining unit comprises a first shear steel sheet 1, a second shear steel sheet 5 and a third shear steel sheet 6 which are arranged at intervals. In actual production, the first shear steel sheet 1, the second shear steel sheet 5 and the third shear steel sheet 6 are rectangular flat steel sheets or H-shaped steel sheets.
Referring to fig. 3, the support core member 2 includes a U-shaped steel member 201 and a connection portion 202. The U-shaped steel member 201 includes a first wing 2011 and a second wing 2012, and a web 2013 connected between the first wing 2011 and the second wing 2012. The plate surface of the web 2013 is perpendicular to the plate surfaces of the first wing plate 2011 and the second wing plate 2012. The first and second wings 2011, 2012 are disposed on opposite sides of the web 2013 and form a U-shaped notch. The connection 202 is connected to the side of the web 2013 facing away from the notch. The two support core members 2 are symmetrically arranged, and the two U-shaped steel members 201 are spaced to form an elongated seam 4. The notches of the two U-shaped steel members 201 are opposite to each other, and a semi-enclosed space S is enclosed. The second shear steel sheets 5 are arranged in the semi-enclosed space S, and the first shear steel sheets 1 and the third shear steel sheets 6 are arranged outside the semi-enclosed space S. The first wing plate 2011, the second wing plate 2012, the first shear steel sheet 1, the second shear steel sheet 5 and the third shear steel sheet 6 are arranged in parallel.

The steel sheet flanges 3021 of two adjacent I-shaped steel sheets 302 are welded, and the steel sheet webs 3022 form energy consumption seams 301 at intervals. During operation, the steel sheet web 3022 is subjected to shear forces. The energy-consuming steel plate 3 is stressed reasonably and is easy to weld.
