      摘要:
      為了提升粘滯阻尼器在隔震曲線梁橋中的減隔震效果盛兴娱乐登陆,本文對其力學性能參數進行優化分析;贏NSYS建立了某三跨隔震曲線連續梁橋的有限元模型,采用非線性動力時程法,分析了粘滯阻尼器速度指數和阻尼系數等參數對地震作用下支座位移和墩底剪力的影響,并確定了粘滯阻尼器參數的合理取值范圍盛兴娱乐登陆。在此基礎上,基于零階優化算法,以墩底剪力絕對值之和為目標函數,對粘滯阻尼器進行了參數優化盛兴娱乐登陆,并對比分析了優化前后的減震效果盛兴娱乐登陆。結果表明:阻尼系數對支座位移和墩底剪力的影響十分顯著;速度指數對支座位移和墩底剪力的影響與阻尼系數有關盛兴娱乐登陆;粘滯阻尼器參數優化后,支座切向和徑向位移減震率分別在47%和22.2%以上,中墩支座的切向位移減震率高于邊墩支座,而邊墩支座的徑向位移減震率高于中墩支座;邊、中墩切向剪力差值由956 kN減小為220 kN,徑向剪力差值由441 kN減小為130 kN盛兴娱乐登陆,其受力相對更為均衡。
