| 組合梁斜拉橋穩(wěn)定性影響因素研究(49 卷) |
| 英文標(biāo)題 |
| Study of influential factors on stability of combined girder cable-stayed bridge |
| 摘要 |
| 研究了橋面板剪力滯效應(yīng)對(duì)結(jié)構(gòu)極限承載力的影響，計(jì)算結(jié)果顯示某些階段安全系數(shù)出現(xiàn)大幅下降，最大變化已達(dá)到42.4%；針對(duì)組合梁斜拉橋鋼主梁(工字形加勁截面)橫橋向抗彎剛度較小，橋面板還未安裝時(shí)容易在橫橋向發(fā)生局部失穩(wěn)的現(xiàn)象，研究了鋼主梁局部失穩(wěn)對(duì)組合梁斜拉橋全過(guò)程 |
