| 標(biāo)題 |
| 橋塔參數(shù)變化對(duì)多塔斜拉橋整體剛度的影響(50 卷) |
| 英文標(biāo)題 |
| Effect of bridge pylons parameters change on general rigidity of cable-stayed bridge with many pylons |
| 摘要 |
| 橋塔是控制多塔斜拉橋整體剛度的關(guān)鍵部分，結(jié)合某黃河公路斜拉橋用有限元軟件SAP2000進(jìn)行建模，計(jì)算分析了橋塔剛度及橋塔高度對(duì)多塔斜拉橋整體剛度的影響，得出橋塔剛度在一定范圍內(nèi)增加時(shí)對(duì)結(jié)構(gòu)位移影響非常顯著，并且得到橋塔高度變化對(duì)多塔斜拉橋影響的變化規(guī)律。 |
