Friction pendulum support capable of realizing longitudinal sliding and transverse damping
The invention belongs to the technical field of bridge supports, and particularly discloses a friction pendulum support capable of realizing longitudinal sliding and transverse damping. The friction pendulum support comprises an upper support plate, a spherical crown, a lower support plate and a bottom plate, wherein the bottom surface of the upper support plate is matched with the top surface of the spherical crown in shape; the spherical crown comprises a first spherical surface close to the upper support plate and a first arc surface close to the lower support plate, wherein the first spherical surface is a convex spherical surface, and the first arc surface is a convex arc surface; the lower support plate is embedded in the bottom plate, and the top face of the lower support plate is matched with the first arc surface in shape; the lower support plate is fixedly connected with a limiting plate through a shear pin, wherein the limiting plate is arranged on the lower support plate; and the limiting plate is arranged on the periphery of the upper support plate, and the limiting plate is fixedly connected with the upper support plate through a pin shaft arranged along the transverse bridge direction. The whole support can slide in the longitudinal direction, meanwhile, under the earthquake working condition, the shear pin is sheared off, the support is converted into the friction pendulum support, and damping is achieved.
本发明属于桥梁支座技术领域，并具体公开了一种纵向滑动横向减震的摩擦摆支座。包括上支座板、球冠、下支座板以及底板，上支座板的底面与所述球冠顶面形状相适应；球冠包括靠近所述上支座板设置的第一球面以及靠近下支座板设置的第一弧面，第一球面为凸球面，第一弧面为凸弧面；下支座板嵌设于所述底板内，且所述下支座板的顶面与所述第一弧面的形状相适应，该下支座板通过剪力销与设于所述下支座板上的限位板固定连接，所述限位板设于所述上支座板的外周，且该限位板通过沿横桥方向设置的销轴与所述上支座板固定连接。本发明既能实现支座整体在纵向完成滑动，同时，在地震工况下，剪力销被剪断，支座转为摩擦摆支座，实现减震。
