peak acceleration

The final result shows that the stress peak value of the tunnel is reduced by 95% with the foamed concrete backfill layers, and dynamic parameter such as acceleration and displacement is attenuated to a certain extent.

计算结果表明，增加泡沫混凝土耗能层后，坑道结构的应力峰值衰减了95%以上，加速度和位移等运动参数也有不同程度的降低。

Under the premise of fitting the target acceleration response spectrum, the peak ground velocity is obtained by a separate adjustment of long period component of the ground motion Fourier Spectrum.

在拟合目标加速度反应谱的前提下，通过单独调整傅立叶谱中较长周期成分来控制合成地震动峰值速度和位移。

Dependence of peak acceleration and peak velocity on the environment shear stress

峰值速度和加速度对环境剪应力的依赖性

The Maximum displacement of nodes increases slowly with earthquake peak acceleration increasing, and the steel arch truss under the earthquake occurs strength failure finally. 2.

研究所得结论主要有以下几点：1、钢管拱桁架在地震作用下，最大节点位移随着地震加速度峰值增大缓慢增加，最终结构发生强度破坏。

In this paper, a method, which synthesizes the artificial ground motion compatible with the specified peak velocity as well as the target acceleration response spectrum, was proposed.

提出一种以绝对加速度反应谱和峰值速度为目标的合成人造地震动时程的方法。
