Some New Developments in Prestressed Concrete
Two ways of approach to prestressed concrete are considered, and results of research discussed. Recent tests carried out on composite partially prestressed bridge slabs by the Civil Engineer’s Department, The Railway Executive, Eastern Region, are described and some results of fatigue tests mentioned. The essential features of prestressed concrete are investigated by distinguishing five different cases of under-reinforced
prestressed concrete beams and three classes of prestressed concrete (monolithic members with bonded steel, monolithic members with non-bonded steel, and an assembly of blocks without adhesion at the joints and non-bonded steel).
