| 不同高墩形式下連續(xù)剛構(gòu)橋動(dòng)力性能分析(50 卷) |

| Dynamic performance analysis of continuous rigid-framed bridge with different forms of high piers |
| 摘要 |
| 應(yīng)用有限元程序ANSYS，分析了杏溝大橋采用鋼筋混凝土四柱式實(shí)心橋墩、雙薄壁式實(shí)心墩、獨(dú)柱實(shí)心墩時(shí)的動(dòng)力性能。研究表明：在橋墩截面積相等條件下，這三類橋梁自振頻率依次增大，且采用四柱式實(shí)心墩和雙薄壁式實(shí)心墩的橋梁振型較為接近，而與獨(dú)柱式實(shí)心橋墩相差較大。前兩類 |
