Experimental investigations on the ultimate strength of ship hull structures mainly involve the following aspects: first, the similarity theory is applied to determine the scope of the model test; then, based on the similarity theory, a reasonable experimental model is designed. Subsequently, based on the principal particulars and structural data of the actual ship, the loading method and boundary constraints of the experimental model are determined. Structural model testing can provide valuable insight into structural behaviors that cannot be accurately predicted solely by theoretical analysis.
In this paper, the authors employ the experimental model method to investigate the structural behavior of river sea ships under pure torsional loading. Based on the results of the experimental model analysis, the relationship between the applied load, structural deformation, and structural strength is established, thereby providing a basis for the calculation and structural design of the river-sea ships structures.
