Abstract
The utility model provides a but shake and decrease quick prosthetic box steel bridge mound of normal position, cushion cap including setting up in the ground lower part is in with setting up the box steel bridge mound body of cushion cap top, this internal connection steel column that is provided with of box steel bridge mound, it is in to connect steel column fixed mounting on the cushion cap, be provided with a plurality of mild steel damper on the lateral surface of connection steel column, but mild steel damper has polylith elastic deformation's mild steel board. Through at this internal mild steel damper that sets up of box steel bridge mound, the mild steel board, can produce and shear the surrender because plasticity is better relatively as mild steel damper's power consumption board, absorbs most seismic energy, and guard box shaped steel pier does not take place destruction well, and anti -seismic performance is better. Simultaneously, because the mild steel board detachable, behind strong earthquake, can take off the replacement with impaired mild steel board and be undamaged mild steel board, realize shaking the quick restoration in back.
Description
Technical field
The utility model relates to a kind of anti-seismic construction of steel bridge pier, damaged after especially a kind of earthquake can the box steel pier of in-situ rapid renovation.
Background technology
The intellectuality of urban development and the earthquake resistant structure of sustainability to industrialization of construction industry and engineering structures propose new requirement and challenge, wherein, realize structure earthquake and repair the basic demand and important research direction that the fast quick-recovery with building function is " can restore funcitons city " fast.Restorability energy structure refers generally to not need reparation or appropriateness reparation can recover the building structure of its performance after structure meets with earthquake, the research and development of restorability energy structure and applying, not only can significantly reduce direct seismic damage loss, and significantly can shorten the rear repairing efficiency of shake, fundamental technics support can be provided in restore funcitons city for finally realizing.
The advantages such as the toughness that steel work is good because steel have, ductility and high strength, are widely used in the country that earthquake is multiple.Especially in the advanced country such as the U.S., Japan that earthquake is multiple, utilize the ductility of steel, apply the bridge pier of steel work in urban viaduct construction, but be not that steel have good ductility, steel structure pier just has good anti-seismic performance.In nineteen ninety-five the big earthquakes in Osaka and Kobe,Japan, not only the bridge pier of concrete structure suffers badly damaged, and steel structure pier also there occurs serious flexing and collapse.For this reason, the anti-seismic performance of steel structure pier obtains the concern of scholar, and anti-seismic idea is also from only considering that the ultimate bearing capacity of bridge pier turns to the direction such as ductility and seismic energy absorption of bridge pier.Conventional reinforcement means has steel bridge pier fill concrete, stiffening rib reinforcement and increases low yield strength energy absorption sections etc., and these reinforcement means all embody the ductility improving bridge pier and the design philosophy significantly not increasing its intensity.
Increase bridge pier that energy absorption sections reinforces when meeting with earthquake for adopting, after shake, infringement maintenance becomes simple, usually only need check and repair energy absorption sections, and without the need to the anchorage element on the basis and suspension column that check bridge.In China, the example building urban viaduct with steel structure pier is gradually many, but the research in the anti-seismic performance of steel structure pier is also little.In view of this, the present inventor furthers investigate the problems referred to above, then has this case to produce.
