Description
Technical field
The utility model is related to a kind of bridge piers, more particularly, to a kind of queen post steel bridge pier.
Background technology
China is located between circum-Pacific seismic belt and Eurasian earthquake zone, and most area is earthquake territory, especially western
Area is mostly meizoseismal area.Bridge is the multi-purpose project on transportation lifeline, once by eaerthquake damage, can not only be brought huge
Economic loss, and can cause rescue personnel that cannot be in time due to its damage, interruption, in turn result in immeasurable personnel
Injures and deaths.In addition, the bridge to wreck its shake after repair it is extremely difficult and costly, after the calamity for seriously affecting earthquake-stricken area
Production and living and reconstruction.Therefore, earthquake is that bridge has to one of risk factors considered.
Main member of the bridge pier as bridge plays vital, a large amount of earthquakes to the whole anti-seismic performance of bridge
Show collapsing mainly as caused by the shock resistance deficiency of bridge pier for bridge.Bridge pier mainly has reinforced concrete bridge at present
Pier, concrete pier of steel tube and steel bridge pier etc..Reinforced concrete bridge pier is answered extensively since its rigidity is big and expenditure of construction is low
Among China's infrastructure, but its ductility and energy dissipation capacity are relatively poor, and existing earthquake shows：Reinforced concrete bridge pier
Damage location mainly appears on bottom or top, or even can cause the total Collapse of bridge, and is difficult to repair after shaking and restores it
Normal usage function.Concrete pier of steel tube only improves the intensity of the bridge pier for armored concrete, same
The problem same with reinforced concrete bridge pier can be encountered.Steel bridge pier not only has good anti-seismic performance and intensity, also has certainly
Heavy and light, floor space be small, can be quickly renovation reinforced after quick construction and shake the advantages that, with China's expanding economy, gradually
It is actually used by China's engineering.
The structure type of steel bridge pier mainly has open side type steel bridge pier and queen post steel bridge pier.Current existing queen post steel bridge
Pier is equally faced with function the problem of being difficult to fast quick-recovery after shake, and to seriously affect, the disaster relief after shake is emergent and restoration and reconstruction work
Make, social economy is restored and people's life causes to seriously affect.In addition, showing earthquake according to multinomial research and case
Load can be such that bridge structure vibrates, generate acceleration, and then generate inertia force, make the connecting portion of structure be easy to happen by
Curved destruction, that is to say, that under the action of earthquake load, easily plasticity occurs for the bottom and top of queen post steel bridge pier ontology even
Buckling failure, so that the queen post steel bridge pier anti-seismic performance of existing structure is poor.
