Structure system.
Background technique
China is earthquake-prone countries, is located between circum-Pacific seismic belt and Eurasian earthquake zone.Bridge is as lifeline
It is big to repair difficulty once casualties and economic loss are serious by eaerthquake damage for the important component of engineering.In addition, bridge
Beam damage also results in interruption of communication, influences the development of disaster relief work after shake, so that rescue personnel can not rush in time, disaster relief object
Money can not be sent in time, to aggravate the degree of seismic secondary disaster.Therefore, the anti-seismic performance of bridge is especially paid close attention to.
Currently, the bridge pier structure based on Ductility Design, moment of flexure of the potential plastic hinge region under geological process is larger,
It occur frequently that destroying.Once plastic hinge region generates serious destruction, bridge pier will generate larger offset, and be difficult to repair, it has to face
The problem of facing reconstruction.As can be seen that there are three aspects currently based on the bridge pier Aseismic Structure System of ductility: first is that
Current bridge pier structure plastic hinge region deformability is insufficient, often destroys after shake seriously, concrete damage destruction leads to plastic hinge
Bearing capacity decline;Second is that biggish residual displacement is caused in plastic hinge region after seriously destroying, it is difficult to repair;Third is that shake rear abutment is difficult
To repair, plastic hinge region is non-exchange, and elasticity is usually kept other than plastic hinge region, all rebuilds and leads and economic loss can be caused to increase
Greatly.
Novel bridge structural system based on recoverable function after shake or fast quick-recovery function is the hair of Future Projects antidetonation
Exhibition trend.Pier will not only keep biggish bearing capacity, it is also necessary to have biggish deformability, while require to shake
