Shock absorption and isolation support with additional frictional damping
The invention provides a seismic mitigation and isolation support with additional friction damping, which comprises a damper and a top seat plate, an upper seat plate, a middle seat plate and a lower seat plate which are sequentially arranged from top to bottom, the damper comprises a piston rod, a cylinder body, a first end cover and a second end cover, one end of the cylinder body is connected with the first end cover, the other end of the cylinder body is connected with the second end cover, and 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 seismic mitigation and isolation support with the additional friction damping has the good functions of high energy consumption, vertical drawing resistance and beam falling prevention at the limit displacement position, and the actual working condition requirement of a high-intensity seismic area can be met. And 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减隔震支座，包括阻尼器以及自上至下依次设置的顶座板、上座板、中座板、下座板，阻尼器包括活塞杆、缸体、第一端盖、第二端盖，缸体的一端与第一端盖连接，另一端与第二端盖连接，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；本发明所述的一种附加摩擦阻尼的减隔震支座，具有良好的高耗能、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的实际工况要求。对于高烈度地震区的桥梁或者建筑结构而言，也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。
