The static strength of a full-scale steel-sandwich composite structure under the condition of 0.1 MPa uniform load was tested and verified,and the strength of plate frame structure under the ac-tion of uniform load was calculated by finite element method,and the differences between different loading methods were discussed.The results show that the structure is not damaged under the design load of 0.1MPa,and the error between the finite element calculation results and the experimental cal-culation results is within 10％,so the finite element method has high calculation accuracy.
