- W3042289461 abstract "In order to accurately identify damage of bridge under natural excitation, an analytical solution of local stiffness of simply supported beam structure is established by using structural mechanics method through establishing the moving load model of simply supported beam. On this basis, an accurate identification method of local damage of beam structure under vehicle load is proposed. Firstly, the local bending stiffness is described in terms of equal length intervals. Secondly, the corresponding loading methods are established for single concentrated load and two-axle vehicle respectively, and the local bending stiffness values of each interval are solved by analytic equation established by node displacement. Damage information can be identified by comparing the flexural stiffness values of simply supported beams before and after damage. Based on the discreteness of local bending stiffness of simply supported beams and the change of local bending stiffness caused by damage, the location and degree of local damage of beams can be accurately identified." @default.
