【 摘 要 】

Filled with Expanded Polystyrene (EPS) foamed concrete, pultruded sandwich panels (PSPs) become stiffer and stronger. The filling transforms the failure of the PSP from core shear failure to mono-cell skin fracture, and the flexural load capacity which are increased by 87.73 %, 217.74 %, 295.02 %, and 683.58 % respectively with different packing density can be greatly improved. To reveal the foam-filling effect, theoretical analyses were performed to predict the rigidity, the peak load, and the failure style of the foam-filled PSPs through introducing mono-cell deformation analysis based on the elastoplastic foundation beam theory. The factors affecting the failure pattern and flexural load capacity were discussed.
