| 標(biāo)題 |
| 連續(xù)鋼桁梁橋節(jié)點(diǎn)剛度對(duì)結(jié)構(gòu)受力的影響研究(49 卷) |
| 英文標(biāo)題 |
| Study about effect of nodal stiffness of continuous steel truss girder bridge on internal forces in structure |
| 摘要 |
| 在大跨度鋼桁梁橋設(shè)計(jì)中，桿件連接設(shè)計(jì)是一個(gè)重要環(huán)節(jié)。鋼橋節(jié)點(diǎn)連接中各板件的尺寸較大，形成一種近似剛性的連接，節(jié)點(diǎn)的剛度對(duì)結(jié)構(gòu)的受力有著不可忽略的影響。針對(duì)東新贛江大橋進(jìn)行有限元分析，對(duì)節(jié)點(diǎn)鉸接、節(jié)點(diǎn)剛接與考慮梁端剛域的情況進(jìn)行了定量比較，得到節(jié)點(diǎn)剛度與結(jié) |
