例如，塔尖在强风中会有2米的摆幅，但是特殊的机制可以吸收这种震动，使塔保持原位。
For instance the spire of the tower during such winds can be deflected by one meter but special mechanisms to absorb the vibrations that keep the tower in position.
破坏是由荷载幅值和循环加载效应的联合作用引起这一事实，较好地解释了地震动三要素对结构破坏的影响。
The truth structure destruction is decided by the combination action of load breadth and circular load effect explains preferably effect three essential of earthquake motions to structure destroy.
但是真实地震动的归一化自相关函数则有一较显著的随机噪声项，这个随机噪声的幅值为0。15左右，这就是本文中所说的超随机特性。
But the normalized auto-correlation of real seismic acceleration record comprises an obviously random noise with amplitude value of 0.15 or so, that is so called super random content.
在频域内，场地的地震动傅立叶幅值谱，可以表示为震源谱、传播路径影响因子和场地效应的乘积。
The Fourier amplitude spectrum used in a seismological model can be expressed as a product of source spectrum, propagation path factor and site effect in frequency domain.
引入结构屈服水平系数，建立了结构的延性需求谱，使地震动的幅值特性和频谱特性可以分开考虑。
By introducing the yielding level factor and constructing the ductility demand spectrum, the characteristic of peak values and frequency contents of ground motions are considered separately.
孔压随震动幅值增大、持时延长而变得更高；
The pore pressure gradually increases as the input motion amplitude becomes larger and the shaking duration becomes longer.
在近场地震动作用下双层隧道下层的地震应力幅值要比上层的地震应力幅值大，在远场地震动作用下则相反；
The seismic stress amplitude of the lower layer is larger than that of the upper layer under near-field ground motion, and under far-field ground motion the condition is opposite.
地震动时程记录是一个明显的非平稳过程，不仅体现在时程幅值强度分布上，更体现在各频率成分上。
