| 摘 要： | 概率一致反应谱通常高估设计地震动的中长周期成份，不能真实代表地震环境下的样本实现，为了合理地估计设计地震动反应谱，本文结合工程结合的动力特性和峰值加速度的经验设防标准，建议了一种重大工程设定的地震确定方法，然后依据设定地震和地震动衰减关系确定设计地震动反应谱。

| Abstract: | The middle-long period contents of earthquake response spectrum evaluated by the earthquake risk probability consistent method are usually higher than that of the standard spectrum given by aseismic design codes,which leads to that it is difficult to apply them for practical problems.In this paper,reasonable determination of the response spectrum of design earthquake for critical engineering is proposed by considering the dynamic property of practical engineering and the design standard of peak acceleration.Based on the design ground motion and its attenuation law,the response spectrum of design ground motion is given. |
