摘要:
为降低村镇地区建造隔震房屋的成本,在钢筋沥青隔震层和隔震墩的基础上做了进一步的改进,提出了钢隔震墩。介绍了框架模型和钢隔震墩的设计,对钢隔震墩在框架结构中的应用进行振动台模拟地震动试验研究,并对钢隔震墩中填充和未填充沥青油膏的隔震性能进行对比分析。基于上部结构的加速度折减系数、隔震前和隔震后的加速度时程曲线以及上部结构相对于台面的最大位移变化的数据分析,证明了钢隔震墩在框架结构中具有良好的工作性能和隔震效果,验证了钢隔震墩中加入沥青油膏可以有效的折减地震作用下的加速度反应,有效地减小上部结构的位移。
Abstract:
In order to reduce the cost of building isolated houses in villages and towns, this paper made further improvements on the basis of reinforced asphalt seismically isolated layer and reinforced concrete asphalt isolation pier,and invented steel isolation piers. This paper introduces the design of the model and the steel isolation pier, and verifies the practicability and reliability of the steel isolation pier in the frame structure through shaking table tests, and makes a comparative analysis of the isolation performance of the steel isolation pier filled with and unfilled with asphalt ointment. Based on the data analysis of the acceleration reduction factor of the superstructure, the acceleration time history curve before and after isolation,and the maximum displacement of the superstructure relative to the table top. it is verified that the steel isolation pier can effectively reduce the acceleration response under earthquake action and effectively control the displacement of the superstructure.
