应用离散小波变换方法将地震动分解为频带互不重叠的相邻小波分量,计算在一致输入及考虑行波效应的非一致激励作用下,大跨结构的位移反应规律。比较两种激励的计算结果,考察行波效应对结构位移。
Discrete wavelet transform is used to decompose ground motion into adjacent wavelet components with no overlap in frequency. The displacement response law of long-span structure under uniform input and non-consistent excitation considering traveling wave effect is calculated. Comparing the results of two kinds of stimuli, we study the traveling wave effect on the structural displacement.
