     this article deals with the free vibration analysis and determination of seismic parameters of a t-shape frame which consists of a continuous beam and a column connected to each other by means of a semi-rigid khorjini connection. firstly, a closed-form solution is proposed and then, a numerical analysis is performed for some comparison and validation purposes. the closed-form solution is developed by solving the frame equations of motion, directly. for this reason, some mathematical techniques such as fourier transform and the well-known complementary solutions are utilized. afterwards, the free vibration parameters of the frame are attained. these parameters are also obtained using finite element method as a numerical analysis and it is observed that the results obtained by this approach are completely coincident with the result of closed-form solution. finally, seismic parameters of the frame and seismic behavior of the semi-rigid khorjini connection for different cases are investigated and their results are compared.
