Description
Technical field
The present invention relates to traffic engineering field, specifically be the one in bridges in highway engineering field
Buckling-restrained energy-dissipation and processing technology thereof.
Background technology
China is positioned at the world two violent earthquake band---circum-Pacific seismic belt and Eurasian earthquake zone it
Between, extruded by Pacific-oceanic plate, Indian and Philippine Sea plate, Earthquake Fault Zone ten
Divide active.Every year earthquake disaster all can occur, it will cause collapsing of China's a large amount of traffic bridge,
Huge threat is brought to the life security of our people, every year due to the impact of earthquake disaster,
China by scold heavily money shake after science of bridge building build work.Buckling-restrained energy-dissipation is as one
Plant outstanding dissipative member, will well ensure the safety of bridge structure, building structure etc.,
Thus reach to protect life security and the property safety of our people, it is described as in earthquake resistant engineering
" electric fuse ".In recent years, buckling-restrained energy-dissipation is in countries such as the U.S., Japan, China Taiwan
It is widely used with in regional traffic science of bridge building, structural engineering.So far,
Buckling-restrained energy-dissipation application in China's engineering is more and more extensive, builds up or in the application built
The bridge structure of buckling-restrained energy-dissipation and building structure reach hundreds of.
Buckling-restrained energy-dissipation mainly includes core primary structure member and restraining tube device.Bearing
During external load, due to the effect of contraction of peripheral constraint transposition, core primary structure member is made in earthquake
Under with, total cross-section enters surrender power consumption state, and then reaches to protect the purpose of building.Anti-in the wrong
Bent energy dissipation brace is consistent with common bracing members or reinforced concrete support function, but the former can
To be greatly improved the utilization rate of steel performance, effectively prevent traditional support generation overall collapse phenomenon,
Improve rigidity and the ductility of structure；And the Hysteresis Behavior that steel can be utilized can consume due to
Horizontal loads has great significance in the upper energy of structure, the shock resistance raising to structure.
At present, buckling-restrained energy-dissipation structural form both domestic and external substantially can be divided into two big classes:
1. clean steel class buckling-restrained energy-dissipation；2. steel-concrete class buckling-restrained energy-dissipation.But China
On market, existing energy dissipation brace is the most uneconomical, the steel of clean steel class buckling-restrained energy-dissipation
Large usage quantity, supports deadweight relatively big, and cost of manufacture is bigger；Steel-concrete class anti-buckling energy-consumption props up
The deadweight of support is relatively big, and owing to the resistance to tension of concrete is very poor, crushes at concrete cracking
Afterwards, easily occur inside restraint device that weak part, constraint transposition can not effectively retrain
Live the cripling of core primary structure member, thus cause the destruction of buckling-restrained energy-dissipation；Along with
Developing rapidly of national economy, crossing-fiver bridge structure, bridge spanning the sea structure, large cantilever bridge are tied
Structures etc. get more and more, and anti-buckling support needs bigger length and bearing capacity, typically now
Way is enlarging section area, and this not only can affect the aesthetic property of structure, also will make the profit of material
Have a greatly reduced quality by rate.So, employing buckling-restrained energy-dissipation designed by stable control method is
Most economical rational method.
Summary of the invention
In order to overcome the steel large usage quantity of prior art buckling-restrained energy-dissipation, deadweight relatively big, system
Make the deficiency that cost is limited compared with big, length and bearing capacity, the invention provides a kind of steel that reduces and use
Amount, alleviate deadweight, reduce cost of manufacture, be applicable to large-span structure, get over Rotating fields, large cantilever
Structure and the combined type buckling-restrained energy-dissipation of big floor height structure and processing technology thereof.
