This paper examines the feasibility of using jointless, thermally restrained construction for railway viaducts. Prima facie, it demonstrates that such superstructures are technically acceptable for both strength and fatigue limit states. It also shows that the abutments and piers can be designed satisfactorily. Such construction is most likely to be economic for multispan viaducts. It is likely to show considerable economies in service; unlike conventional construction, there are no incompatibilities of thermal movement between the rails, superstructure and substructure, maintenance costs should therefore be reduced. (A) For the covering abstract see IRRD 873218.
