Sažetak
In order to solve the problem of lighting in the building structure, landscape area or car city and the vehicle yard to achieve green energy saving, it is proposed to replace the full concrete bridge deck scheme with the glass bridge deck and concrete bridge deck, and to utilize the light transmittance of the glass material. In order to explore the technical feasibility of applying glass bridge panels to automobile passages, the paper intends to carry out the bearing capacity test of three-layer PVB glass sheets and single-layer glass bridge decks under different wheel pressures under the wheel load, paying attention to the continuity of load application and researching the load, respectively the force of the glass plate when acting in different positions. Six laminated glass plates and three single-layer glass plates were designed and fabricated, and the rubber load was used to simulate the wheel load for test loading. The ratio of the bearing edge and the plate angle of the single-layer glass to the load at the center of the plate was 78.7% and 64.8%, respectively. The ratio of the bearing edge of the laminated glass and the plate angle of the laminated glass to the load was 98.3% and 86.5%, respectively. For laminated glass, the effect of the load position on the ultimate bearing capacity of the glass sheet is weaker than that of the single layer glass. The ultimate bearing capacity under wheel load acting on the center, side and corner of the laminated glass plate is 2.78, 3.47 and 3.66 times of that of the laminated glass plate at the same position. The test results in this paper can be of practical value for the further application of glass bridge panels in engineering applications.
