大跨度橋梁抗震設(shè)計(jì)和振動(dòng)控制的研究與應(yīng)用現(xiàn)狀

本文介紹了大跨度橋梁抗震設(shè)計(jì)的現(xiàn)狀和所面臨的困難, 指出對(duì)大跨度橋梁合理的抗震分析方法應(yīng)當(dāng)
進(jìn)行多點(diǎn)激勵(lì)隨機(jī)地震反應(yīng)分析, 并對(duì)地震輸入問(wèn)題、隨機(jī)地震動(dòng)場(chǎng)的模擬和地震反應(yīng)分析方法作了介紹。

后側(cè)重介紹了結(jié)構(gòu)振動(dòng)控制技術(shù)的研究現(xiàn)狀及其在大跨度橋梁中的應(yīng)用。

This article describes the seismic design of long-span bridges the current situation and the difficulties faced by that of the large span bridge seismic analysis methods should be reasonable
 Multi-excitation stochastic seismic response analysis, the problem of earthquake input, random earthquake ground motion simulation and seismic response analysis method are introduced. Most
 Introduced after the focus on structural vibration control technology and its status of long-span bridges.
