Italian seismic amplification factors for peak ground acceleration and peak ground velocity

open access: yesJournal of Maps, 2022
Ground motion modification over large areas is generally evaluated by focusing on source effects disregarding local lithostratigraphic site conditions. Hence, amplification maps of peak ground acceleration and peak ground velocity are proposed to improve

地震动峰值特征参数对土坡地震响应的规律研究

open access: yesDizhen xuebao, 2021
本文随机选取了100条具有不同地震动峰值特征参数的地震动记录,通过基线校正、积分等方法获取每条地震动的峰值加速度(PGA)、峰值速度(PGV)和峰值位移(PGD)三个参数,进而基于有限元数值模拟,通过对比同一个观测点不同峰值特征参数的特性与不同观测点同一峰值特征参数的特性来研究土坡的地震响应规律,分析各地震动峰值特征参数与土坡地震响应的相关性。计算结果表明:PGA,PGV和PGD与土坡地震响应都具有良好的正相关性,其相关性系数平均值分别为0.868,0.981,0.926 ...

ANALISIS GROUND VIBRATION DENGAN METODE PEAK PARTICLE VELOCITY (PPV)

open access: yesFaktor Exacta, 2021
<p><em>Measurement of Peak Particle Velocity (PPV) mm / sec in the Sabo dam construction project was carried out using seismic accelerometers. This study is to determine the value of PPV produced by construction equipment and then compared with the BS 6472-2: 2008 standard. The measurement method is carried out based on the applicable rules.

面向地下结构的最优地震动峰值指标随埋深变化规律

open access: yesDizhen xuebao, 2022
选取了50条实际地震动,采用一维场地等效线性化方法分别对均匀半空间场地和成层半空间场地进行地震响应分析,同时选择效益性作为判别标准来探究最优地震动峰值指标(峰值加速度PGA,峰值速度PGV,峰值位移PGD)随埋深变化的规律。研究结果表明:对于选取的两类场地,最优地震动峰值指标均随埋深的改变而变化,埋深浅时PGA效益性最优,随着埋深的增加,效益性最优逐渐由PGA转变至PGV;PGA与PGV转折的交点位置随场地剪切波速的不同而不同,且该转折交点位置与场地剪切波速呈线性相关。

Note on scaling of peak ground acceleration and peak ground velocity with magnitude [PDF]

open access: yesGeophysical Journal International, 2002
SUMMARY The theoretical scaling of near-field peak ground acceleration and peak ground velocity with moment magnitude, Mw, is found using an L model of rupture. This scaling matches well with the magnitude scaling of recent attenuation relations.
