摘要
Abstract
On the background of a new bridge constructed in the site of an old one in Shao Xing,Zhe Jiang province,China,four different models are created by Doctorbridge and Midas Civil.By analysing the stages of the construction and completion of the new bridge,the results are comparaed.And the results show that if the overall structure are just focused,the union section model and the additional section model are accurate enough to satisfy the actual engineering;and if the overall and local structure are both focused,such as shear lag effect of the deck,partial load effect and the cross beams,both of the three girders model and the plate and double girders model are reliable.Besides,the stress improvement approaches of the negative moment area of the composite beams are discussed,some related results provide a guidance to the future similar projects.关键词
