Experimental work with model concrete shells is described. The shells were 9 ft long, 3 ft wide and 1/2 in. thick. Seventeen shells were tested, the main purpose of the tests being to examine the stresses near the end traverse, and particularly in the corner of the shell. The results are compared with those obtained analytically (a) when the disturbance from the longitudinal straight edge is considered and (b) when the disturbance from the curved end is also taken into account. The latter analysis predicts much higher corner stresses than the former. Although the experimental results are generally in better agreement with the first method of analysis, stresses considerably in excess of this were encountered in some instances. W.M. Newman and A.S.

In retrospect it can be seen that the celebration of our Golden Jubilee in 1958 set the final seal upon the Institution as a chartered body of eminence and importance; it was in effect the end of the beginning.

This paper outlines the aims and policy of the European Economic Community and poses the basic questions that British engineers will ask about working in or out of the Community. James N. Lowe
