The question of factor of safety on reinforced rete desian is now foremost in enqineers’ minds. This has been brought about by shortage of reinforcing steel and the issuance of directives increasing the permissible steel stresses. In this paper the authors question the practice of a uniform factor of safety on dead and live load and suggest a method of de- sign which they believe would permit a better distrr- bution of reinforcing steel than could be obtained ping a prestressed wire around it to give the structural properties for water lines in which R ipe igh hydrostatic pressures can be carried. A hint as to possible use of pipe of this type for culvert purposes is included.
