| 摘 要： | 针对某港区汽车下河码头的架空斜坡道,采用有限元软件MIDAS分别建立其简支梁和连续梁结构的瞬态动力模型,数模计算结果表明:在最不利工况下,连续梁跨中的最大位移和最大弯矩均小于简支梁结构,连续梁可比简支梁节省纵向配筋约10％,本研究的结论可供类似工程参考.

| Abstract: | As for the overhead ramp of car Ro-Ro wharf in some port area,the finite element software MIDAS is used to build structural transient dynamic models respectively for simple supported beam and continuous beam.According to the numerical model computing result,the maximum displacement and bending moment at the span centre of continuous beam structure are less than that of simple supported beam structure under the most adverse working condition.And longitudinal reinforcement of continuous beam structure is 10 %... |
