Continuity of prismatic and shell saw-tooth sheds through their window planes

A new method of calculation of north-light sheds is presented. The sheds considered are of one span and consecutive shed units are connected-apart from the window posts-by a solid wall for a short length in the window plane near the two supports. It is shown that this connexion creates a kind of fixation of the sheds in the form of a restraining moment acting in the horizontal direction, causing a reduction of the maximum compressive stresses at the centre of the span at the top of the gutter beam to about one-third the value it would take if each unit were unconnected to other shed units on either side. Sheds connected in the manner mentioned can be built to cover much bigger spans. The extra quantity of concrete required for the attachment of consecutive sheds is negligible while economy in the longitudinal reinforcement can be achieved. Amin Ghali
