vertical seismic excitation

基本解釋

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.
采用有限元程序計算分析了該拱橋在豎向地震動行波輸入和一致輸入下的動力反應(yīng)，通過結(jié)果對比反映出行波地震反應(yīng)并不簡單隨波速單調(diào)變化的現(xiàn)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.
以兩種典型空間結(jié)構(gòu)為研究對象，考察了豎向地震作用下結(jié)構(gòu)的地震反應(yīng)以及豎向多點(diǎn)輸入對結(jié)構(gòu)地震反應(yīng)的影響。
