设计地震 meaning in English
design earthquake
operating-basis earthquake
Examples
- Study of seismic effects and seismic dynamic parameters of a large pumped storage power station site
大型抽水蓄能电站场地地震动效应及设计地震动参数研究 - A model used pga , pgv and pgd for calibrating seismic response spectrum was introduced
介绍了用地面峰值加速度( pga ) 、峰值速度( pgv )和峰值位移( pgd )三个参数标定设计地震反应谱的模型。 - But in fact their design response spectrum could be very different so that the parameters of ground motion for building design could be improper
实际上，两者可以相差很多，由此确定的设计地震动参数势必不尽合理。 - Factually there is no assurance for ductility in this coefficient . furthermore , the seismic force is comparatively lower in design than in fact . both of them necessarily increase the seismic risk
实际规范中并没有延性构造保证，加之我国当前设计地震作用相对偏低，更增加了地震破坏的危险性。 - After considering the influences of the tensility performance and ratio of damping on the earthquake action of steel structure , the reference formula to design the earthquake force based on the is given
在考虑了钢结构的延性性能、阻尼比等因素对结构地震作用的影响之后，给出了采用概率延性调整系数的设计地震力的参考公式。
