The Design and Construction of the New Basic-Bessemer Plant at Port Talbot

Mr. SNOW in his brief introduction of the paper referred to the sudden death of Sir Alfred LeMaitre who deserved the credit for the inspiration of Gatwick and who guided the project through the initial teething trouble; to the support given by the Minister of Transport and Civil Aviation, Mr. Harold Watkinson and to the excellent team spirit which was built up and made the job such a happy one. Mr. FINN then described and illustrated some of the works involved at Gatwick.

The Institution welcomes as its President for the Session 1959-1960, Mr. L. E. Kent, B.SC., M.I. STRUCT. E., M.I.C.E.,who takes ofice on the 1st October.

THE normal method for determining the collapse load for a framed structure involves the assumption of several collapse modes and the calculation of the appropriate load system. For highly redundant structures, this procedure can be extremely time consuming in spite of the use of various theorems which have been derived. This paper describes a non-linear circuit element which reproduces the buckling or yielding behaviour of structural members. These elements may then be connected into networks representing framed structures and their behaviour under load studied. N. L. Svensson
