High-precision earthquake identification type friction pendulum seismic mitigation and isolation support
The invention provides a high-precision earthquake identification type friction pendulum seismic mitigation and isolation support, and belongs to the technical field of bridge supports. The support comprises an upper seat plate, a lower seat plate, a spherical crown lining plate, a limiting guide plate, a shear pin and the like. A through rectangular sliding window is formed in the middle of the limiting guide plate. The shear pin is provided with an annular shearing groove. The limiting guide plate of an integral structure is adopted and is fixed by the shear pins which are uniformly arranged in a circumferential manner, so that the two sides of the support can be guided to be stressed simultaneously, and the horizontal shear force in each direction of the bridge is consistent. Meanwhile, the shear pin and the annular shear groove are corrected based on the shear strength of the alloy steel which is purchased in batches and is produced by the same manufacturer, the same batch and the same process, the matching precision of the actual shear force and the designed shear force is improved, and accurate earthquake recognition is achieved. After the shear pin is cut off and fails, the limiting guide plate falls off and does not limit the lower seat plate any more, the support can freely swing in a reciprocating mode in the horizontal direction, earthquake energy input is reduced, and the seismic reduction and isolation function is achieved.
本发明提供一种高精度地震识别型摩擦摆减隔震支座，属于桥梁支座技术领域。该支座包括上座板、下座板、球冠衬板、限位导向板和剪力销等。限位导向板中部开设有贯通的矩形滑动窗口。剪力销上具有环向剪断槽。本发明采用整体结构的限位导向板并由圆周方式均匀布置的剪力销固定，可保证支座两侧导向同时受力，实现桥梁各个方向上的水平剪力一致。同时，本发明基于批量采购的同厂家、同批次、同工艺的合金钢的抗剪强度对剪力销以及环向剪断槽进行修正，提高实际剪断力与设计剪断力匹配精度，实现地震精准识别；剪力销剪断失效后，限位导向板脱落不再对下座板限位，支座可进行水平向的往复自由摆动，降低地震能量输入，实现减隔震功能。
