ABSTRACT
The design of reinforced and prestressed concrete has been increasingly codified during the past 40 years. Before the Second World War, recommendations for design had been published in the UK in a Code of Practice prepared by the Department of Scientific and Industrial Research, which was issued in 1934, I and in the Building By-laws of the London County Council of 1938. 2 After the war, the DSIR Code was revised and became the British Standard Code of Practice, CP 114, in 1948. 3
The Institution of Structural Engineers published its First Report on Prestressed Concrete in 1951/ which gave design procedures for prestressed construction. This report was subsequently revised and issued as BS Code of Practice, CP 115, in 19597 The BS Code of Practice for the Design of Precast Concrete, CP 116, 6 appeared in 1965 and supplemented the two earlier BS codes. By this time, a number of codes dealing with specialized forms of concrete construction were being prepared. Codes of Practice 114, 115 and 116 have been updated from time to time and are currently adopted as deemed-to-satisfy documents in the Building Regulations.
