The Inspection Requirements For Bailey Bridge

Bailey bridge is widely used in various traffic engineering projects. It has the characteristics of simple structure, convenient transportation, quick erection, large load-bearing capacity, good interchangeability, and strong adaptability. When inspecting Bailey bridge, not only the bridge itself but also the inspection stand should be inspected. The inspection stand is an experimental bench used to test the stiffness and strength of Bailey bridge. Therefore, it is required that the stiffness and strength of the inspection stand can meet the measurement requirements when the Bailey bridge bears an external load exceeding the yield stress. Therefore, it is necessary to obtain the limit load of the inspection stand. From the finite element analysis results above, it can be seen that the strength and stiffness of the inspection stand need to meet the engineering requirements under the pressure of external load. In order to obtain the limit load of the inspection stand, the principle of approaching can be adopted, gradually increasing the external load until the strength approaches the yield limit.
