matlab开发-Earthquakesimulation。地面加速度记录采用非静态Kanai–Tajimi模型进行模拟。
代码片段和文件信息
%% Simulation of ground acceleration record
% Time series of acceleration records are simulated using a stationnary
% process that is “weighted“ by an envelopp function. The function that
% fullfills this procedure is ‘seismSim‘.
%
% Then we try to retrieve the parameters of the simulated seismic record by
% using the function ‘fitKT‘
clear all;close all;clc;
f = linspace(0402048); % frequency vector
zeta = 0.3; % bandwidth of the earthquake excitation.
sigma = 0.3; % standard deviation of the excitation.
fn =5; % dominant frequency of the earthquake excitation (Hz).
T90 = 0.3; % value of the envelop function at 90 percent of the duration.
eps = 0.4; % normalized duration time when ground motion achieves peak.
tn = 30; % duration of ground motion (seconds).
