The finite element technique is adopted for calculating the modal frequencies of a T-type Timoshenko frame. The axially inertia effect of each branch is included. The ratio of the radius of gyration of a cross-sectional area to length is defined as r. Both the effects of r and the element number of each branch on the relative error of the first modal frequency are studied. A concentrated load moving on the frame is treated as an example. The velocity effect of load on both maximum displacement and moment of the frame is also investigated. These results are compared with those of a Bernoulli-Euler frame.
