摘要 研究某高烈度区(8度,0.2 g)近断层学校建筑隔震设计,以新疆某学校建筑基础隔震设计为例。基于水平减震系数法,建立学校建筑基础隔震的设计流程,详细分析设计流程各阶段的模型选择,荷载取值,工况组合,计算指标的限值及依据,尤其分析探讨了核心的隔震层设计。研究结果表明:基础隔震技术实现了对上部结构设计降一度设计的性能目标,不但可以保证结构安全,震后还可以充当应急避难场所提供有效保障。其可为同类建筑,基础隔震设计提供借鉴。 The isolation design of a school building near fault in a high-intensity area(8 degrees,0.2g)is studied.Taking the foundation isolation design of a school building in Xinjiang as an example,based on the method of horizontal shock absorption coefficient,the design process of the foundation isolation of the school building is established,and the model selection,load value,working condition combination,calculation index limit and basis are elaborated in each stage of the design process.Especially,the core seismic isolation layer design is analyzed and discussed.The research results show that the foundation isolation technology can achieve the performance goal of reducing the degree of superstructure design,not only can ensure the safety of the structure,but also can serve as an effective guarantee for the emergency shelter after the earthquake,and it can provide a reference for the base isolation design of similar buildings..
