With the development of bridge structures, it is very necessary to ascertain load-bearing characteristic of complex structures. Model test can directly response complex mechanical characteristics. Based on the model test of 1:5 T-beam, this paper introduces the factors of designing model beam, and gives some similarity relation between model beam and prototype beam, including the deflection and stress similarity relation. So this paper laid a theoretical foundation for the later model test.
