After visits in previous years to Bristol, Edinburgh, Newcastle, Paris, and Manchester, this year the History Group chose Glasgow for its annual 3-day study meeting. Arrangements were made from London by Julia Elton and John Bancroft, as before, while this time our invaluable Scottish helpers were mainly Roland Paxton and Gordon Masterton. On the evening of our arrival, they set up an exhibition of drawings and old photographs and outlined the visits they had planned for the next 3 days.
A description is given of experimental tests on 15 steel panels, each fabricated by spot welding steel face plates onto a corrugated steel core to form a sandwich. This form of construction is being investigated with a view to its use as decking on offshore platforms. All the panels had plan dimensions of 2.1 m x l m and cores consisting of top-hat stiffeners (Fig 1) of depth 60 mm, placed side by side. Each panel was tested by subjection to uniform lateral (z-direction, Fig l) loading over its entire surface, firstly when simply supported along all boundaries and then when simply supported across its y-direction boundaries only.

The application of the ABAQUS finite element package to the analysis of a troughed-core steel sandwich panel (Fig 2) is described, and the results are compared with those of closed solutions and experimental testing. Panels of this kind, which promise good strength-to-weight and strength-to-stiffness ratios, are of interest as lightweight decking for offshore platforms. The panel had high bending and shear stiffnesses in the x-direction (Fig l), i.e. the direction of the core troughs, and low bending and shear stiffnesses in the y-direction. It had a length-to-breadth ratio of 3 and a span-to-depth ratio of about 56, with a self-weight of 62 kg/m2. Subjected to a uniformly distributed z-direction load of 10 kN/m2 over its entire surface, it experienced an experimental central deflection of span/l33 when simply supported across its y-direction edges only and of span/428 when simply supported along all four edges.
