【摘要】：提出一种球形抗震支座,介绍其构造及工作机理,并利用MIDAS/Gen分析其设计参数。研究结果表明:与以往支座相比,新型球形抗震支座的抗震性能得到一定程度的提高,具有结构简单、抗震性能稳定、可靠、耐久等特点。通过设置限位销和弹性限位槽,实现了支座在多遇地震和罕遇地震作用下的刚度切换以抵抗不同水平的地震作用。
[Abstract]:A spherical seismic bearing is proposed, its structure and working mechanism are introduced, and its design parameters are analyzed by MIDAS/Gen. The results show that the seismic performance of the new spherical seismic bearing is improved to a certain extent compared with the former one. The structure is simple, the seismic performance is stable, reliable and durable. By setting the limit pin and the elastic limit slot, the stiffness switch of the bearing under the action of frequent and rare earthquakes is realized to resist the earthquake action at different levels.
