In order to study the bearing capacity of the vehicle glass bridge deck structure, the displacement sensor is used to measure the deformation of the glass panel, and the strain gauge is used to measure the change rule of the strain on the outer surface of the glass panel, and the failure mode, the load-displacement curve, safety performance and stiffness requirements of the glass plate under different boundary conditions and the most unfavorable load position are analyzed. The results show that the ultimate bearing capacity of a single glass plate supported on both sides is about 53.7% of that of a simple glass plate supported on four sides, and that of laminated glass plate supported on both sides is about 66.7% of that of a simple glass plate supported on four sides. The deformation of the glass plate is the largest when the load acts on the center of the plate, and the stress of the glass plate is the largest when the load acts on the corner of the plate. From the perspective of meeting the structural strength requirements, the load acting on the corner of the plate is the most unfavorable working condition, and from the perspective of meeting the structural stiffness requirements, the load acting on the center of the plate is the most unfavorable working condition. Under the two most unfavorable conditions of plate angle and plate center position, applied 0.8, 1.0, 1.2, 1.5, 1.8 and 2.0 times of wheel load, the maximum strain and deformation of laminated glass plate can meet the requirements of the code. The test results can provide a reference for the practical engineering of vehicle glass bridge plate. [ABSTRACT FROM AUTHOR] |
