| 正交異性鋼橋面梯形閉口加勁肋厚度的優(yōu)化(49 卷) |
| 英文標(biāo)題 |
| Optimum of thickness of trapezoid closed stiffened rib of orthotropic steel bridge deck |
| 摘要 |
| 針對(duì)鋼箱梁正交異性橋面局部受力復(fù)雜的情況，運(yùn)用ALGOR有限元軟件建立了鋼箱梁結(jié)構(gòu)分析的板殼單元空間有限元模型。采用車輛荷載在橫橋向的不利位置布載，分析了正交異性鋼橋面系梯形閉口肋厚度對(duì)橋面承載性能的影響，給出了加勁肋厚度的建議取值及對(duì)正交異性鋼橋面系的優(yōu)化措 |
