The aim of the paper is to improve the current shape limitation requirements of BS 5400: Part 3, which are known to be unduly conservative, especially when applied to assessment of existing structures. A practical method for finding the local critical stress for plate/stiffener combinations, without limitations on section slenderness, is presented. The critical component is identified for all possible buckling wavelengths, which can vary between the length of the stiffened plate and the wavelength of an encastré plate or stiffener, depending on the section geometry. For each possible wavelength, the critical stress c$ the critical component is found, when restrained by the other component, using an iterative method thut is easily programed for a desktop computer. Validation is provided by 75 finite element (FE) solutions. The
results will be incorporated in a methodfor design or assessment.

Dr W.W.L. Chan (F) I congratulate the authors (and thank them!) on their excellent and timely paper, drawing together some 25 years’ statistical data on gas explosions. At last we have a rational basis for reviewing acceptable risk and accidental design pressure!

Andel's Wings and Cotton Reels

Construction work for two new footbridges across the Thames at Charing Cross is about to begin. Pedestrians crossing the river will soon have the benefit of wide, modem walkways and impressive views upstream to the Palace of Westminster and downstream to St Paul’s Cathedral. The bridges are unique and their design and construction present new challenges to engineers, architects and contractors. John Parker

<h4>Stainless Steel in Fire</h4>

Stainless Steel in Fire

Due to their durability, aesthetic appeal and corrosion resistance, the use of stainless steels in construction is continuously increasing. Eurocode 3:Part l.4 covers the design of structural stainless steels and was issued in 1996. There is, however, a shortage of design guidance on the fire resistance of structural stainless steels, and this hinders the materials’ wider use in certain applications. Nancy Badoo
