A brief outline of the basic-Bessemer converter process is given to illustrate the close connection between plant and structure in a modern steelworks of this kind. Special features of the foundations and building, such as the shape and construction of the roof, crane girders, platform block and telpher system are described, followed by notes on the use made of welding and high-strength pre-stressed bolts and the method of gantry rail fixing. An account of the erection sequence and anti-corrosion treatment is also given. J. W. P. Jaffe
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
