| 一種新型鐵路鋼—混組合桁架橋的動(dòng)力特性分析(51 卷) |
| 英文標(biāo)題 |
| Dynamic analysis of new type of railway steel-concrete composite trussed bridge |
| 摘要 |
| 對(duì)一種由三角形桁架和混凝土槽形板組成的新型鐵路鋼—混凝土組合桁架橋建立了有限元計(jì)算模型，分別采用空間梁單元、空間板單元及三維實(shí)體單元對(duì)混凝土槽形板進(jìn)行模擬。計(jì)算分析了橋梁的自振特性和移動(dòng)列車荷載作用下的動(dòng)力響應(yīng)。結(jié)果表明：采用三種不同單元模擬槽形板得到的 |
