| Abstract: | Taking the design of long-span capping beam in an urban bridge project as an example,the article analyzes the influence of the capping beam and the stud linear rigidity ratio on the inner force distribution of structure and adopts two different kinds of the finite element calculation software to calculate and compare the long-span capping beam.The influence of pile base rigidity should be considered during building up the structural model.The relative contents can be referred for the design of the similar b... |
