Continuous steel-concrete composite bridges develop longitudinal tensile stresses in their deck slab as a result of differential strains caused by shrinkage. Analytical procedures are described whereby the shrinkage stresses along continuous, non-uniform composite beams can be estimated. The accuracy of these predictions is assessed in relation to the results of a laboratory test on a two-span continuous beam. In addition, existing design recommendations are examined and typical distributions of stresses in medium span bridges are presented. A.E. Long and P. Csagoly
I shall confine myself to fairly obvious generalities when dealing with the subject of housing. But the fact that a generality is obvious does not mean that it is universally perceived. It is one of the features of British life that the more obvious a generality, the less likely it is to be noticed. Lord Goodman
Mr. Gordon Rose's dilemma in establishing the capacity of load-bearing walls of old buildings to the satisfaction of Authority (April) has drawn further comment; Mr. Stephen Revesz (F) considers it is timely to air this issue and offers practical, commonsense suggestions drawn from experience. He writes: We have had to deal with similar problems when converting existing buildings. In most cases the floors were found to be just adequate for domestic loading (1.5 kN/m2) but had been in use as offices for a considerable number of years. The owners had controlled storage of papers or office machinery to avoid overloading by commonsense. Verulam
