The transfer of stress between two walls that are connected by beams, when the walls are subjected to different axial stresses, is evaluated. Methods of calculation are given for the following cases : firstly, when loads are applied during construction and therefore affect only the section of the frame already constructed; and secondly, when loads are applied after completion of the structure. A solution for the case of unequal stresses applied at the top of the structure is implied in the first method. The solutions are based on the simplification that the beams connecting the two walls can be replaced by a continuous connecting medium. Expressions are given for the total shear in the connecting medium, measured from the top of the wall to any point along the height of the wall, for the local beam shears and for the horizontal deflection of the walls.

The conditions for the 13th Biennial Competition for the Drury Medal, founded by the late Mr. F. E. Drury (Past President) are now available.

Following an outline of the events forming the background to the project, the authors have set down their approach to the decisions which were required at the various stages of its development. The major disciplines are stated and reasons for the choice of the particular layout, articulation, materials and finishes finally adopted are given. W.A.F. Fairhurst, A. Beveridge and G.F. Farquhar
