【摘要】 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。更多还原

【Abstract】 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),some ideas about structureal design under medium earthquake are suggested,and some methods of structureal design under medium earthquake in the condition of actual code and design are proposed.更多还原
