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。
This paper presented a new spherical seismic bearing and introduced its structural characteristics and working mechanism,and a series of design parameters were analyzed by using MIDAS/Gen. The conclusion was that new spherical seismic bearing had better seismic performance than the previous bearings with a simple structure,and it had stable and reliable seismic performance characteristics. By using a spacer pin and an elastic limit groove,the seismic bearing could resist earthquake action in different earthquake levels by changing its stiffness.
