Description
Technical field
The invention belongs to construction engineering technical field, it is related to a kind of earthquake and exempts from damage being layered prefabricated assembled self-resetting swinging steel
Frame structure system.
Background technology
Steel construction has the advantages that high intensity, light-weight, ductility and good toughness, though have over one hundred year developing history, so far
It is that sustainable development requirement is best suited in various widely applied structural materials that the present, which appoints, and in historical progress considerably long from now on
It remains to show its energy-saving and environmental protection, green advantage.Both the central and local governments in 2017 are successive about the policy of development assembled architecture
It puts into effect, all parts of the country are respectively provided with assembled architecture related work target, put into effect related support policy.Newly-built assembled at home
It is mostly prefabricated assembled concrete structure type in building, and it is actually rare at present in China's prefabrication and assembly construction steel construction, but steel
Structure has environmental protection, energy saving；Short construction period is constructed not by seasonal effect；Increase residence space usable floor area；Subtract
Few building waste, construction material is repeatable to be utilized；Anti-seismic performance well equal remarkable advantages, will certainly allow prefabricated assembled steel construction at
For the developing direction of future architecture.And《Building industry modernization development outline》In explicitly point out, built to the year two thousand twenty assembled
Build 20% or more the ratio for accounting for new building；50% or more the ratio of new building is accounted for assembled architecture in 2025, it is seen that dress
Market development space with formula steel construction is huge.
The Mexico Ctiy earthquakes occurred in 1985, are sent out the U.S.'s Loma Prieta earthquakes occurred in 1989 for 1994
The Hyogo-ken Nanbu earthquakes of raw U.S.'s Northbridge earthquakes, nineteen ninety-five Japan's generation, all give a large amount of conventional junction
It has been configured to the damage of unrepairable, has caused thousands of casualties, economic loss is in terms of 10,000,000,000 dollars.Due to earthquake
The uncertainty and complexity of effect, structure are possible to by the geological process than fortification intensity bigger, cause structure seriously by
Damage.Such as the regional pervious fortification intensity in 2008 in Wenchuan is 7 degree, and Wenchuan earthquake epicentral intensity is up to 11 degree, personnel
For injures and deaths with missing more than 80,000 people, direct economic loss is more than 840,000,000,000 yuans.Even if structure is on the ground by fortification intensity
Do not collapse after shake, but has partial component because destroying the particularity of position and destroying seriousness makes it be difficult to reinforce and repair
It is multiple, it finally can only also rebuild, bring huge loss, while also inevitably affect the production of people, life.2009
January in year, America and Japan scholar was put forward for the first time in the earthquake engineering second stage Cooperative Research Program meeting of NEES/E-Defense America and Japan
" recoverable function city (resilient city) ", and it is counted as the future developing trend of earthquake engineering research.By reasonable
Design, work out and do not occur to destroy in earthquake or only occur that the structure of destruction can be repaired rapidly in certain particular elements, be
The important topic of sustainability earthquake-resistant structure.Recoverable function structure (earthquake-resilient structure) from
This becomes one of scholars and engineer's focus of attention.
Current existing self-resetting swinging steel frame structural system is mostly to fasten additional Self-resetting in traditional steel structure body to shake
The research put core to realize, and wave core about Self-resetting energy consumption at present mostly uses presstressed reinforcing steel realization and waves core runback
Position, but presstressed reinforcing steel needs live tensioning, work progress cumbersome.Presstressed reinforcing steel and the anchoring construction on basis are difficult or even practical
It is difficult to realize in engineering.And the fastener of presstressed reinforcing steel will produce loosening for a long time, cause the stress relaxation of presstressed reinforcing steel, seriously
Influence structural behaviour.The deformability of presstressed reinforcing steel is limited, if in seismic process, moderate finite deformation, prestressing force occur for structure
The strain of muscle is more than its yield strain, then needs to presstressed reinforcing steel replace after shaking and anchor again, tensioning, process it is cumbersome and
It is expensive.It is realized currently, plastic deformation mainly occurs by metal damper under geological process for the energy consumption for waving core.
Some researches show that after one earthquake is generated compared with large plastometric set, energy dissipation capacity significantly reduces metal damper, can not ensure
Safety of the structure under aftershock effect.Difficult, all replacements are dismantled since metal damper generates larger plastic deformation, after shake
Expense it is also higher.And the existing steel frame structural system that waves cannot be satisfied industrialized production, the requirement of prefabricated construction.This
Invention is based on the above problem and proposes.
