Abstract：Segmented model experiments are the most real and effective method of researching wave loads, which simulates the elastic effect of the hull effectively. Since the backbone model simulates the stiffness of real ship truly is essential, which directly determines whether the segmented model experiment simulates the real physical phenomena or not. The existing keel girder models domestic and foreign were reviewed. A channel-section keel girder was proposed which better simulates the hull structure with large opening in deck. The method of stress measurement was introduced and viability was proved by test. The process of designing channel-section girder was introduced with an example, at last validation of the results was made based on migration matrix method.
