Spherical support with additional frictional damping
The invention provides a spherical support with additional friction damping. The spherical support comprises a damper, an upper seat plate, a middle seat plate and a lower seat plate, a plane friction pair is arranged between the upper seat plate and the middle seat plate, and a spherical friction pair is arranged between the middle seat plate and the lower seat plate; the damper comprises a piston rod, a cylinder body, an upper end cover and a lower end cover, one end of the cylinder body is connected with the upper end cover, the other end of the cylinder body is connected with the lower end cover, the cylinder body is provided with an inner cavity, the piston rod comprises a friction piston, the friction piston is arranged in the inner cavity, and at least part of the inner cavity wall of the cylinder body can be in interference fit with the friction piston; the structure has the functions of high energy consumption, vertical drawing resistance and beam falling prevention at a limit displacement position, and can meet the actual working condition requirements of a high-intensity earthquake area. For a bridge or a building structure in a high-intensity earthquake area, a tensile structure, an energy consumption structure and a beam falling prevention structure do not need to be additionally arranged, the structural complexity of an anti-seismic structural system is reduced, and construction, installation and daily maintenance are facilitated.
本发明提供了一种附加摩擦阻尼的球型支座，包括阻尼器以及自上至下依次设置的上座板、中座板、下座板，上座板、中座板之间设置平面摩擦副，中座板、下座板之间设置球面摩擦副；阻尼器包括活塞杆、缸体、上端盖、下端盖，缸体的一端与上端盖连接，另一端与下端盖连接，缸体具有内腔，活塞杆包括摩擦活塞，摩擦活塞被设置在内腔中，缸体的至少部分内腔壁能够与摩擦活塞过盈配合；本发明具有高耗能、竖向抗拉拔以及极限位移处防落梁的功能，能够满足高烈度地震区实际工况要求。对于高烈度地震区的桥梁或者建筑结构而言，无需额外设置抗拉结构、耗能结构以及防落梁结构，有利于降低抗震结构体系的结构复杂程度，便于施工安装以及日常维护。
