Seismic Isolation Design of School Building Foundation Near Fault In An Eight-degree Area
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 combina-tion,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 e-mergency shelter after the earthquake,and it can provide a reference for the base isolation design of similar buildings..
