| Abstract: | parative prestressed box-girder has goodappearance andexcellent bending capability and torsional capability,it can also use high strength materials effectively.So they are usedin many bridges.The researching of the method ofcalculating coefficients of transverse distribution of load to box-girder is important in bridge designing.Thedissertation mainly analyzes the distribution of live load among the girders in the mid span.Comparingthe result of the finite element method with thatof manual method,the conclusion isadvantages and disadvantages of the two methods,and their application value. |
