摘要
对一个9度区的酒店建筑进行了基础隔震设计与分析。分析结果表明,隔震支座参数设计合理,隔震层各项指标均满足规范要求,上部结构水平地震作用可降低1.5度设计。经过隔震设计的建筑,其抗震性能得到提高。
The based-isolation structure of a hotel in area of fortification intensity 9 is analyzed and designed. The results of calculation and analysis show that the design parameter of isolation bearing is reasonable and the indexes of isolation layer meet the requirements of Chinese seismic code. It shows that the intensity of horizontal seismic action can reduce 1. 5 degree to upper structure based on Chinese seismic code. The seismic behavior of upper structure is improved by isolation.
