    In a previous paper [1] grillages in which no torsion developed were analysed to find their natural frequencies. This paper is directed to the task of analysing similar grillages in which torsion in the members is present. To accommodate the torsional vibrations the terms "dynamic torsional stiffness and carry-over factor" have been introduced and these are used in conjunction with the dynamic flexural functions of the previous paper. © 1968.
