［摘要］国内规范对于隔震设计的相关规定大多是指导性、原则性的，理论解释较简单，实际应用却会遇到许多问题。以层间隔震为例，在性能化设计过程中，如何实现与上下部结构相匹配的性能标准，同时又不至于设计过于保守，采用单一计算模型难以实现，需要对上下部结构或构件采用不同的计算模型和内力调整来完成设计，这使得设计的技术门槛过高，影响了隔震设计的广泛推广。结合两个具体的隔震工程，对隔震的设计思路、计算模型适用条件、参数的合理选取及具体的实现方法进行深入探讨。

Abstract: Specifications for isolation design related regulations are mostly guidance, principle, simple theoretical understanding, and the practical application has many problems. To layer interval shock as an example, in the performance-based design process, how to realize the top and bottom structure matching performance standards, at the same time unapt too conservative design, using a single calculation model is difficult to realize. It need to top and bottom structure or component using different calculation model and adjustment of internal force to complete the design. This makes that design technology threshold is high, and the isolation design difficulty is increase. Combined with two engineering examples of seismic insulation design, the discussion is focused on the design method of seismic isolation, the applicable condition of the calculating model, rational selection of the parameter and implements method.

Keywords: isolation design; damping ratio; earthquake-reduction coefficient; coefficient; torsion
