Problems solved by technology

The existing steel-composite material buckling-restrained braces have better corrosion resistance and lower maintenance requirements than traditional buckling-restrained braces. The potential of the overall molding process of composite materials is fully realized, and GFRP (Fiber reinforced plastic, glass fiber composite material) cannot completely wrap all the surface of the steel core, and the steel core may still corrode where there is no GFRP wrap
In addition, there is still a lot of room for improvement in the energy dissipation performance of this type of support.

Embodiment Construction

[0018] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0019] Such as Figure 1-5 As shown, a maintenance-free non-buckling steel-composite material energy-dissipating support, including energy-dissipating steel core 1, outsourcing GFRP5, GFRP supporting ribs 6 and filling foam 7, the energy-dissipating steel core 1 is in the shape of a line or a cross Runs through outsourced GFRP5;

[0020] The energy-dissipating support is longitudinally divided into a constrained section 2, a flexible section 3 and a connecting section 4, the constrained section 2 is located in the middle, the two sides of the constrained section 2 are flexible sections 3, and the outside of the flexible section 3 is a connecting section 4; Section 2, flexible section 3 and connecting section 4 have the same width; the constrained section 2 has the largest thickness, which is equal to the sum of the thickness of energy-dissipat...

Abstract

The invention discloses a maintenance-free buckling-free steel-composite material energy-consuming support. The maintenance-free buckling-free steel-composite material energy-consuming support comprises an energy-consuming steel core, an outer packaging GFRP (glass fiber reinforced polymer), a GFRP supporting rib plate and filling foam, wherein the energy-consuming steel core penetrates through the outer packaging GFRP in a straight mode or a crossed mode; the energy-consuming support is longitudinally divided into a restrain section, flexible sections and connecting sections, wherein the restrain section is arranged in the middle, the flexible sections are arranged at the two sides of the restrain section, and the connecting sections are arranged at the outer sides of the flexible sections; filling foam is arranged between the outer-layer GFRP in the restrain section and the flexible sections and the energy-consuming steel core; the GFRP supporting rib plate connecting the outer-layer FGRP with the energy-consuming steel core is arranged in the restrain section; a bolt hole for connecting a bolt is formed in each connecting section; the bolt holes penetrate through the outer-layer GFRP and the energy-consuming steel core. The maintenance-free buckling-free steel-composite material energy-consuming support has the advantages of being light in weight, free of maintenance, resistant to corrosion, excellent in energy-consuming performance, and free of bending in steel core.

Description

technical field [0001] The invention relates to the technical field of building structures, in particular to a maintenance-free non-buckling steel-composite material energy dissipation support. Background technique [0002] The existing buckling-constrained bracing can better improve the dynamic characteristics of the structure and improve its anti-vibration or anti-seismic performance. The existing steel-composite material buckling-restrained braces have better corrosion resistance and lower maintenance requirements than traditional buckling-restrained braces. The potential of the overall molding process of composite materials is fully realized, and GFRP (Fiber reinforced plastic, glass fiber composite material) cannot completely wrap all the surfaces of the steel core, and the steel core may still corrode where there is no GFRP wrap. In addition, there is still a lot of room for improvement in the energy dissipation performance of this type of support. Contents of the i...
