Formula, higher anti-side rigidity can be provided for steel frame can provide additional damping again, take the lead in entering modeling under earthquake motion effect
Property, energy consumption mechanism is played to reduce the response of earthquake motion flowering structure.
Buckling support is mainly by support inner core, outsourcing confining part and soap-free emulsion polymeization material set between these
Expect three parts composition.Under middle shake or big shake effect, due to the sidewise restraint by outsourcing confining part, inner core is supported to surrender section
Energy total cross-section sufficiently surrenders dissipation seismic energy under state tension or in compression, therefore this support not only solves common branch
The problem of support is easy to happen compression overall collapse, local buckling and low-cycle fatigue fracture under big shake, while also acting as damage control
The effect of system is brought convenience to repairing after the shake of main structure.
Nuclear power development becomes the important channel of China's energy sustainable development in recent years, and nuclear island antidetonation is at design of nuclear power plant
One of important topic faced.Often there are a large amount of steel structure platforms inside nuclear island factory building, but due to nuclear island factory building technique, build
The requirement for the profession arrangement such as building causes the span of part steel platform and support load larger, the steel under design basis earthquake effect
The seismic response level of platform is higher, brings to the Aseismic Design of safety-related systems, equipment or pipeline in steel platform huge
Challenge, while increasing the Seismic expense of related system, equipment.The country is existing at present runs and is building nuclear power plant for core
The Aseismic Design of steel structure platform is showed no " energy-dissipating and shock-absorbing " design using buckling restrained brace form to reduce structure in island
Response under earthquake motion.
It is accordingly required in particular to which a kind of buckling restrained brace structure for nuclear island steel construction damping, above-mentioned existing to solve
There are the problem of.
Summary of the invention
The purpose of the present invention is to provide a kind of buckling restrained brace structures for nuclear island steel construction damping, for existing
The deficiency of technology can effectively reduce steel platform structurally ringing under design basis earthquake or even super design reference earthquake
It answers, the Aseismic Design and identification for related system in steel platform and equipment all have considerable economy, can also make nuclear island
Aseismic Design adapt to severeer Seismic Design environment.
Technical problem solved by the invention can be realized using following technical scheme:
A kind of buckling restrained brace structure for nuclear island steel construction damping, which is characterized in that it includes stainless steel outer packed
Casing, prefabricated heat resistance concrete block and support stainless steel inner core, the prefabricated heat resistance concrete block setting are stainless in the outsourcing
In steel sleeve, the support stainless steel inner core is arranged in the stainless steel outer packed casing and the prefabricated heat resistance concrete block
Non-cohesive material is coated on the contact surface of heart position, the support stainless steel inner core and the precast concrete block.
In one embodiment of the invention, the inner cavity setting of the stainless steel outer packed casing is fluted, described prefabricated resistance to
Hot concrete block is arranged in the groove.
In one embodiment of the invention, the stainless steel outer packed casing is divided into two parts symmetrical above and below and abutment joint
It carries out soldering and forms weld seam.
In one embodiment of the invention, it is stayed between the support stainless steel inner core and the prefabricated heat resistance concrete block
It has the gap.
Further, the gap is 1mm to 2mm.
Buckling restrained brace structure for the damping of nuclear island steel construction of the invention, compared with prior art, in structure
Chamber optimizes and by the way of precast concrete block filling, can effectively reduce dead load, keep section smaller, quality can
Control property is higher with mechanical precision；All component materials easily obtain, relative inexpensiveness, and modular manufacturing and assembly can effectively reduce
Time of site operation and improve quality controllability；Suitable for high temperature in nuclear island factory building, high irradiation, high humility and perishable tight
Severe environment, performance are stablized, are achieved the object of the present invention.
