| Abstract: | The article sets forth the basic theory of the shearing force-flexible beam grillage method,and uses MIDAS/Civil to build the beam grillage model and simple-beam model for steel box-beam bridge and concrete box-beam bridge.After the calculation,the vertical displacement is given for the steel box beam and concrete box beam under the loading action so as to validate that the beam grillage method can better simulate the steel box-beam bridge and concrete box-beam bridge.The calculation result can satisfy the engineering precision. |
