运用有限元软件对某桥临时钢混结合段结构进行实体分析,根据运营过程中的最不利荷载工况,分析了在2种最不利工况下的应力状态。结果表明,除部分结合处存在应力集中现象外,结构总体受力合理,应力满足要求。
運用有限元軟件對某橋臨時鋼混結閤段結構進行實體分析,根據運營過程中的最不利荷載工況,分析瞭在2種最不利工況下的應力狀態。結果錶明,除部分結閤處存在應力集中現象外,結構總體受力閤理,應力滿足要求。

The paper analyzed a temporary steel-concrete bridge with finite element software.Accord-ing to the operator during the most unfavorable load cases,two kinds of the most unfavorable stress conditions were analyzed.The results show that the overall structure is in reasonable force state and the stress can meet the requirements in addition to local stress concentration at part junction.
