This paper presents a brief review of durability problems in reinforced concrete structures caused by lack of sufficient concrete cover and a statistical concept to analyse and to quantify in-situ concrete cover in buildings. The use of non-destructive procedures to measure the cover in building elements under construction is discussed. Cover data of a large number of buildings in Australia and Japan were analysed. It was found that the Levels of Confidence (LOC) for achieving minimum concrete cover for durability were poor, with less than 50 per cent of the structures achieving a 90% LOC. The use of the non-destructive technique of cover measurement and the statistical concept to quantify the in-situ cover as a quality auditing tool are described. The effectiveness of such a tool, coupled with a series of corrective measures implemented during the construction, to improve the LOC is demonstrated using an example of projects in Singapore. With improvements in design detailing, selection of suitable spacers and good installation practice, it is suggested that an LOC of 90% could be achieved and should be specified. These, together with the correct choice of the concrete type, cover thickness and good concreting practice, could prove to be the most economical way of achieving the design service life of concrete structures.

The stability of a large lattice shell with radome geometry is investigated numerically using large deflection theory. The theoretical background of the analysis is discussed and the iteration algorithm which utilises the method of orthogonalised load-deflection states is outlined.
