| 基于強(qiáng)度折減系數(shù)譜的規(guī)則橋梁彈塑性地震反應(yīng)分析方法(32 卷) |
| 英文標(biāo)題 |
| Method for the Inelastic Seismic Response Analysis of RegularBridges Based on Strength Reduction Factor Spectrum |
| 摘要 |
| 選用43次地震中獲得的350條地震波，進(jìn)行單自由度（SDOF）系統(tǒng)的非線性時(shí)程分析。運(yùn)用統(tǒng)計(jì)回歸方法，得到4類場(chǎng)地上SDOF系統(tǒng)強(qiáng)度折減系數(shù)與彈性周期和位移延性比的關(guān)系譜。將規(guī)則橋梁等效為SDOF系統(tǒng)，提出利用彈性反應(yīng)譜和強(qiáng)度折減系數(shù)譜計(jì)算規(guī)則橋梁最大彈塑性地震反應(yīng)的簡(jiǎn)化 |
