The Code for Design of Bridges and Culverts of Highway Reinforced Concrete and Prestressed Concrete (hereinafter referred to as the “New Code”) was formulated in Chapter IV of “Code for Design of Highway Bridges and Culverts” (hereinafter referred to as “Bridge Regulations”) published in 1975 - reinforced concrete structures and 1978 Published “Highway Prestressed Concrete Bridge Design Code” (hereinafter referred to as “public pre-regulation”) based on the revised merger. During the revision process, the Ministry of Communications, Highway Planning and Design Institute of the Ministry of Communications, in conjunction with the relevant institutions of higher learning, design and research institutes in the country, conducted a special study on normative content, conducted surveys to solicit opinions and collect information , The new standard is compiled on this basis. Revised main contents are: the original stress-tolerant design of reinforced concrete bridges
