초록
In this study, the loading test and structural analysis were performed on the snow load and the results were compared. The load plates were loadedon the roof surface of the model, and structural analysis was performed under the same conditions. The result of loading test, the maximumdisplacement was observed in the center of the top, and the maximum stress was observed near the bottom point. Displacement and stress were foundto have a high linear relationship with the load. Comparing the structural analysis results with the loading test results, the maximum displacementdifference is 4.5% and the maximum stress difference is 10.2%. It is expected that closer results can be derived if the boundary conditions for thelongitudinal direction of the model are clarified during experiments and analysis.
