| 鉛芯橡膠橋梁隔震支座屈服比的優(yōu)化及設(shè)計應(yīng)用(31 卷) |
| 英文標(biāo)題 |
| Optimization Study on the Yield Ratio of Seismically Isolated Lead Rubber Bridge Bearing and Its Design Application |
| 摘要 |
| 運用有限元軟件SAP2000，建立不同未隔震橋梁自振周期，鉛芯橡膠隔震支座彈性周期、非彈性周期和隔震屈服比的198個單自由度隔震橋梁模型，進行非線性地震能量反應(yīng)分析，研究鉛芯橡膠隔震支座屈服比與其耗能比的關(guān)系以及不同地震水平下的優(yōu)化屈服比。研究表明，隔震支座優(yōu)化屈 |
