Abstract

The invention discloses a manufacturing method of a maintenance-free steel-composite material buckling restrained brace. The method comprises the following steps of: manufacturing core material, and packaging the core material by reinforcing material; filling the core material into a mould; laying a vacuum bag and extracting air; leading resin into mould; and curing the product to obtain the finished product. The whole brace component is molded into a whole for one time by vacuum infusion; the condition that the axial force is mainly born by an inner core stress unit by a telescopic joint structure during the support work is guaranteed; and a support inner core steel core is packaged by glass fiber reinforced polymer (GFRP) composite material on the whole, so that the brace has the characteristic of corrosion resistance. By adopting a GFRP rectangular tube filling-free restraint yield section structure form, the buckling restrained brace has the characteristic of being light in weight.

Description

technical field [0001] The invention belongs to the technical field of manufacturing buckling restraint supports, and in particular relates to a manufacturing method of maintenance-free steel-composite material buckling restraint supports. Background technique [0002] Japan and the United States are countries that carried out research on structural control systems earlier. The complete member of the buckling-restrained brace first appeared in Japan. [0003] The United States began to apply this kind of support in engineering after the Northridge earthquake, and it was called Buckling restrained Brace (BRB for short) according to the mechanical characteristics of the support. Although the research in the United States was later, it developed rapidly relying on its economic and technological advantages. Since 1998, in Utah, Oregon, California and other regions in their high-intensity earthquake areas, buckling-constrained braces have been used in many new constructions and s...
