  We present a simplified expression for the gravitational angular momentum in
the framework of the teleparallel equivalent of general relativity (TEGR). The
expression arises from the constraints equations of the Hamiltonian formulation
of the TEGR. We apply this expression to the calculation of the angular
momentum of plane-fronted gravitational waves in an arbitrary three-dimensional
volume $V$ of space and compare the results with those obtained for linearised
gravitational waves.
