浅谈复杂结构的中震设计

Discussion on seismic design of complicated structure under seismic fortification intensity

复杂结构、超限高层结构在实际工程设计时需要进行中震设计和验算。本文从抗震规范中小震、中震和大震的概念入手,说明了中震设计和验算的工程概念和方法,提出了在现行规范和设计条件下,在实际工程中进行中震设计的设计要点和应注意的一些问题。

It is necessary that complicated structures are analyzed and checked under seismic intensity(medium earthquake).Based on the concept of frequent seismic intensity(low earthquake),seismic fortification intensity(medium earthquake) and very rare seismic fortification intensity(great earthquake),this paper suggests some ideas about structural design under medium earthquake and proposes some methods of structural design under medium earthquake in the condition of actual code and design methods。
