A review is presented of data concerning the occurrence of abnormally heavy highway loads and of severe temperature difference loading on bridges. The probabilities of these loads occurring simultaneously during the design life of a bridge are considered. It is concluded that there is a high probability of combined loading occurring on about 1% of UK trunk-road bridges during their design lives. The probability of the remaining trunk-road bridges experiencing combined loading during their design lives is about 3%. It is almost certain that severe temperature difference loading will occur under dead load conditions. Finally, reduced design loads, based on a nominal ‘permanent’ load, are suggested.

Raft foundations for low-rise buildings In October last year, Mr J. O’Rourke described some methods adopted in the Wrekin District for the construction of raft foundations to counter the effects of mining subsidence. Some amendments to these were suggested by Mr T. Holden Brown in February, but Mr D. R. Robinson, who is with the Poole Borough Council, has now written to express his disagreement with these suggested amendments. He continues: If the cavity is closed by the additional 150mm-thick mass concrete, water running down the cavity will build up on the mass concrete and cause dampness on the inner blockwork and the screed.

The author is indebted to Mr Jackson for a valuable response to the original ‘Viewpoint’ article; it is gratifying that at least one person felt sufficiently moved by the question posed in the title of the article, and in its content, to take the trouble to compose a reply. Mr. D. McQuillan
