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

Application of metaheuristic algorithms in prediction of earthquake peak ground acceleration

open access: yesThe Journal of Engineering, 2023
The seismic resilience of a structure has been evaluated using peak ground acceleration (PGA). Ground motion parameters such as source characteristics, local site conditions are used to forecast the PGA of the ground motion. This paper aims to develop an

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 ...

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.
