Title: $The Application of Grillage Method in the Load Test of Fabricated Small Box-girder Bridge
Abstract: The grillage method is an analytical method of space structure which can provide some data about static deflection and strain of the primary control section,to satisfy the box-girder bridge static test requirements of theoretical calculations.Take the Mao erdong Bridge for study,the use of Midas/civil establishment of bridge girder model and single-girder model.Through the comparison and analysis of the test result to determine grillage method in the load test of Fabricated small box-girder bridge is feasibility,practicality and accuracy,the understanding of the girder theory and fabricated small box girder bridge load test provides reference for the application.
