Embodiment Construction
[0020] Since the anti-buckling energy-dissipating support of the inline cross-section inner core is similar to the specific implementation of the buckling-resistant energy-dissipating support of the cross-section inner core, the present invention will be further described below in conjunction with an embodiment of a cross-section inner core and the accompanying drawings.
[0021] see figure 1 , figure 2 (a) and image 3 (a), an embodiment of the anti-buckling energy-dissipating support consists of four spacers 1, four protective plates 2, four wooden blocks 3, fiber-reinforced composite materials 4, an inner core 5 and 8 limit blocks 6, The inner core 5 can adopt a steel plate member. Wherein the specific shape of each part, the connection of interrelationship and the purpose thereof are as follows.
[0022] see image 3 (a), in this embodiment, the protective plate 2 is an angle steel, the cross section of the wooden block 3 is a square processed by chamfering, and holes...

The invention discloses a fiber-reinforced composite material-wood-steel combined buckling-restrained brace. The fiber-reinforced composite material-wood-steel combined buckling-restrained brace comprises an inner core and an outer combined restraint sleeving the inner core, wherein the outer combined restraint comprises cushion blocks, a plurality of protecting plates, wood blocks and a fiber-reinforced composite material, the protecting plates are arranged on the periphery of the inner core longitudinally, each two adjacent protecting plates are connected through the cushion block arranged at the outer ends of the cushion blocks so as to form an enclosed structure accommodating the inner core, the wood blocks are arranged on the outer surfaces of the protecting plates connectively, and the fiber-reinforced composite material is wound on the integral outside of the cushion blocks, the protecting plates and the wood blocks longitudinally. The fiber-reinforced composite material-wood-steel combined buckling-restrained brace has the advantages of low self weight, short manufacturing period, convenience in transportation, simplicity in mounting and replacement and the like while bearing and energy-dissipating capabilities are guaranteed, can be applied to multi-story buildings and high-rise buildings with concrete structures and steel structures and can solve the problem of safety of building structures under the action of earthquakes.
Description
technical field [0001] The invention belongs to the technical field of building structure engineering and relates to a buckling-resistant energy-consuming support. Background technique [0002] Buckling-resistant energy-dissipating braces have the characteristics of ordinary braces and high energy consumption, effectively overcome the defects of common steel braces that are prone to overall buckling and insufficient seismic capacity, and have been widely used in seismic engineering. At present, the anti-buckling energy-dissipating braces are classified from the perspective of the material of the externally constrained members, which are mainly divided into two types: concrete-constrained anti-buckling energy-dissipating braces and all-steel anti-buckling energy-dissipating braces. Concrete-constrained buckling-resistant energy-dissipating braces have the disadvantages of self-heavy weight, long production cycle, and difficult transportation and installation; all-steel buck...
