Calculation of suspension vehicle structure used to inspect cable-stayed bridges

Abstract

The solution of a suspended vehicle moving under the bridge beam to inspect the cable-stayed bridge is one of the suitable and feasible solutions in the conditions of manufacturing technology in Vietnam. However, this is a special specialized device. During the implementation process, the designer and verifier encountered many difficulties, especially in calculating the vehicle frame structure. Therefore, this paper will present the basis of the design method of suspended vehicle structure for bridge beam inspection. In which the focus is on presenting load analysis methods and testing methods to evaluate structure. The results of this study will contribute to improving the capacity of domestic technical staff and developing localized products. In addition, it will also be the basis for other studies related to this subject in the future.
