Assembly type elastic-plastic energy dissipation device and rigid frame bridge thereof
The invention discloses an assembly type elastic-plastic energy dissipation device and a rigid frame bridge thereof. The assembly type elastic-plastic energy dissipation device comprises a reinforcedconcrete ball pin, a reinforced concrete ball seat and an energy dissipation piece; the reinforced concrete ball pin is hemispherical, and a spherical groove matched with the reinforced concrete ballpin is formed in the reinforced concrete ball seat; the energy dissipation piece comprises a steel pipe, flanges and bolts, the flanges are arranged at the two ends of the steel pipe respectively, andfirst bolt holes for installing the bolts are formed in the flanges; and the inner diameter of the steel pipe is larger than the outer diameter of the reinforced concrete ball seat. The assembly typeelastic-plastic energy dissipation device is arranged between a pier column and an abutment foundation, the axial normal load is borne by a spherical hinge, deformation and energy dissipation neededduring an earthquake are borne by the energy dissipation steel pipe, the stress structure is clear, and the good energy dissipation performance is achieved in application so as to consume energy generated by the earthquake; and large elastic deformation can be generated to adapt to the deformation requirement required by multiple earthquakes.
本发明公开了一种装配式弹塑性耗能装置及其刚构桥，装配式弹塑性耗能装置包括钢筋混凝土球销、钢筋混凝土球座和耗能件；钢筋混凝土球销为半球形，钢筋混凝土球座上设置有与钢筋混凝土球销匹配的球面型凹槽；耗能件包括钢管、法兰盘和螺栓，钢管的两端分别设置有法兰盘，法兰盘上开设有安装螺栓的第一螺栓孔；钢管的内径大于钢筋混凝土球座的外径。本发明通过在墩柱和墩台基础之间设置一个可装配式弹塑性耗能装置，轴向正常荷载由球铰承担，地震时所需变形及耗能则由耗能钢管承担，受力结构更加明确，在应用上具有更好的耗能性能以消耗地震产生的能量；能够产生更大的弹性变形以适应多发地震所需变形要求。
