For this purpose, the concepts on grey earthquake intensity, grey classification of site soil, normality degree of the working of structures and grey reliability of structures are defined.
为此，提出了灰色地震烈度，场地灰类、结构工作正常度以及结构灰色可靠度等概念及其计算方法。
On the other hand, the results of nonlinear earthquake time history analysis show that the base isolation system effects are very well, so the intensity can be reduced from 9 degree to 7 degree.
其次，通过非线性地震反应时程分析，证明隔震效果十分明显，该科技楼的设防烈度可由9度降为7度。
Construction of 8 degree earthquake intensity category C, seismic shear walls for the two levels, "then in the calculation of the anchorage length is, in the end is a few levels ah?"
建筑抗震设防烈度为8度类别为丙类，抗震等级 剪力墙为二级”，那么在计算锚固长度是，到底是几级啊？
