Partial Buttress Reservoir Walls

The paper presents a plastic method of design for plate girder webs which allows for the influence of flange rigidity upon the post buckled behaviour of webs. The design procedure which is based on a study of the behaviour of 40 plate girders tested by the authors, has been checked against other experimental data available in the technical press. Because the present design procedure allows for the influence of flange stiffness upon the post buckled behaviour of shear webs it is more accurate than existing design methods. K.C. Rockey and M. Skaloud

Experimental data are presented showing the influence of reinforcement detailing on structural efficiency for half-joints, joggled splices in columns, flexural corners and in situ concrete beam-column joints. G. Somerville and H.P.J. Taylor

The ‘Stability’ report has taken some time to develop but the timing of its appearance has coincided with a period of very active re-thinking of our basic structural philosophy. In particular, it seems to form the third member of a trilogy which began with the Aims of Structural Design and has coincided with the issue of recommendations on Future Building Regulations.
