Accurate assessment of flexible connection characteristic is very important for structural safety of connectors and very large floating structure (VLFS), and yet model test is necessary measure to acquire flex-ible connection characteristic of VLFS. In this paper, a flexible connector model is designed base on cal-culation results of dynamic response of flexible connectors according to a VLFS with shallow draft and transverse pontoon. Rigidity of the flexible connector model is studied through series static tension and com-pression test with different amplitude and combined load and effect of combined load is also analyzed. Dy-namic response of the flexible connector model is studied through series longitudinal dynamic load test and structural safety and applicability are also verified. Test results show that the flexible connector model is performing well under static and dynamic load and the structure is safety. The measurement results of load, displacement and stress of the flexible connector model can provide a basis for verifying connector struc-tural design and calculation method.
