How can I assemble stiffness matrices with different dimensions?

Its a beam with 3 displacement variables. I use a linear interpolation function for "u" and Hermit cubic interpolation function for "w" and "fi". When calculating stiffness matrix I achieve 3...

How can I employ Galerkin's method to these coupled equations, in order to achieve stiffness matrices?

I cannot transform these two coupled equations to one equation (the technique we use in Timoshenko beam).
