One degree of freedom system

Hello, Is it appropriate in terms of program logic to analyze a system with a single degree of freedom with a 2 x 2 m slab drawn on a single column created in a floor with a height of 3 m in the program? What I want to do is to define a mass at the end of a rod and compare the equivalent earthquake load, response spectrum, and base shear forces that will occur in the time history.
 
Would be appropriate. However, in this system, if you choose a Semi-rigid diaphragm and release the Uz vertical swing, it is not exactly a single degree of freedom system. This approach is correct if your goal is to not recognize a rod and a mass on it, but you should do a rigid diaphragm solution.
