Mr. Parkhouse has presented a simple model to represent a cellular deck without intermediate diaphragms. The model has then been analysed for various loadings to determine the corresponding transverse distribution coefficients based on deflexion and moment. The loadings and deflexions have been represented as a sinusoidal series.
