Abstract

The bending performance is the main performance index of the sandwich structure. This paper is used to analyse and test showing that: the range of the elastic limit and the maximum bearing capacity is 25~30. kN and 34.9~54.8. kN, respectively; the average of bending stiffness and shear stiffness measured by test is 810. kN. m and 1717. kN/m, respectively; In elastic stage (U2 = 6 mm), plate material in the weld junction of web (n = 5)and face plates appear local yield, which shows that the most unfavorable area of sandwich panels is the weld junction of web and face plates.
