vertical seismic excitation

基本解释

The seismic response of the arch bridge under the vertical direction unique support excitation and traveling wave excitation are calculated by the finite element procedure respectively.
采用有限元程序计算分析了该拱桥在竖向地震动行波输入和一致输入下的动力反应，通过结果对比反映出行波地震反应并不简单随波速单调变化的现象。
Seismic responses of two typical large-span structures to uniform vertical seismic excitation are investigated and the effects of multi-support vertical excitation on the responses are checked.
以两种典型空间结构为研究对象，考察了竖向地震作用下结构的地震反应以及竖向多点输入对结构地震反应的影响。
