Description
Technical field
The invention belongs to energy-consumption supporting member, relate to the disaster reduction and prevention field of civil engineering, particularly relate to a kind of novel energy-consumption supporting member-piston type and fill stage clip Self-resetting energy dissipation brace, it has good energy dissipation capacity and Self-resetting function.
Background technology
In January, 2009, America and Japan scholar proposed first using " can the repair function city " general orientation as earthquake engineering cooperation in the earthquake engineering second stage Cooperative Research Program meeting of the NEES/E-defense U.S..Chinese scholar in 2011 specify that the new ideas of seismic design of structures-can restore funcitons structure.Can restore funcitons earthquake resistant structure refer to earthquake (setting up defences or rarely occurred earthquake) after do not need to repair or repair slightly under part using state to recover the structure of its using function, and structural system is easy to build and safeguard, life cycle cost high efficiency.At present, Self-resetting structure mainly comprises three kinds of forms: (1) post-tensioned prestressing bean column node: allow bean column node opening and closing in geological process process, by horizontal prestressing force, structure is resetted; (2) system is waved: allow the vertical supporting member of structure to upwarp in basic junction and wave, by deadweight or vertical prestressing, structure is resetted; (3) Self-resetting supports: support and not only bear energy-dissipating and shock-absorbing effect, provide runback virial that structure is resetted simultaneously.First two Self-resetting structural system all needs to change the original node connected mode of agent structure or vertical bearing system, Self-resetting supports then only needs the original supporting member of replacing structure, and any variation need not be done to agent structure system structure just can be made to have self-resetting capability, thus other self-centering systems have inherent advantage relatively, newly-built structure design or existing structure are reinforced and all has great importance, day by day come into one's own in recent years.
In order to solve the problem of support energy consumption and Self-resetting, Chinese scholars expands large quantity research to it.At present, the principle that the Self-resetting that Chinese scholars has been developed supports according to supporting the generation of Self-resetting restoring force is mainly divided into two classes: energy dissipating portion and Self-resetting system are connected in parallel; Energy dissipating portion and the connection of Self-resetting Cascade System, support section and Self-resetting part are by being connected in series the rigidity and power consumption that increase structure.Wherein mainly be divided into viscous fluid power consumption, friction energy-dissipating and flow of metal power consumption according to support energy consumption principle; Shape-memory alloy wire (twisted wire), steel strand and spring is mainly divided into according to providing restoring force material.Above-mentioned various Self-resetting supports and substantially can both realize self-resetting capability while power consumption, but also there is some shortcomings part, such as energy dissipating portion and the Self-resetting of Self-resetting system parallel connection to support compared with traditional support mostly construct more complicated, require very high to processing technology, and more difficultly find suitable material self-recoverage prestressed material, the work requirements condition of marmem is stricter, and price is more expensive, the automatic recovery ability of high strength steel strand is poor, and the Self-resetting restoring force that spring provides is limited in one's ability; The Self-resetting support structure of energy dissipating portion and Self-resetting Cascade System is simple, but the shape memory alloy bar material stretching out restraining tube unit can not be long, otherwise shape memory alloy bar material possibility compressive buckling, but shape memory alloy bar material can not be too short, otherwise the stress reinforced stage can be entered after shape memory alloy deformation exceedes recoverable strain, marmem only has the ability of bearing, and does not have bearing capacity.Therefore, ensuing research mainly focuses on simple structure, the research and development of the Self-resetting energy dissipation brace that working mechanism is clear and definite.
Summary of the invention
The object of inventing is shaken to solve traditional support large or occur excessive permanent set under middle shake effect and strengthen the problem of shaking rear maintenance and reconstructed cost, and the complex structure of Self-resetting energy dissipation brace is loaded down with trivial details with making processing in a large number at present, and the simple structure proposed, processing and fabricating easily a kind of piston type fills stage clip Self-resetting energy dissipation brace.
The present invention solves the problems of the technologies described above the scheme taked to be: piston type is filled stage clip Self-resetting and supported mainly through friction portion and Self-resetting part to realize good energy dissipation capacity and Self-resetting function.
