A variational formalism of tetrad gravitation theory is developed in the Weyl-Cartan space with independent variations in
the tetrad coefficients, metric tensor components, and affine connectivity coefficients that considers the Weyl condition
imposed on the nonmetricity based on the method of undetermined Lagrange multipliers. The gravitational field equations are
derived for the Lagrangian comprising all possible quadratic convolutions of curvature, torsion, and nonmetricity tensors
in addition to the linear component. Differential identities are obtained for the general gravitational Lagrangian in the
Weyl-Cartan space.
