Design Agencies and Regulations
In the United States, pre-stressed concrete design and construction is aided by organizations such as Post-Tensioning Institute (PTI) and Precast/Prestressed Concrete Institute (PCI). In Canada the Canadian Precast/Prestressed Concrete Institute (CPCI) assumes this role for both post-tensioned and pre-tensioned concrete structures.
Europe also has its own associations and institutes. It is important to note that these organizations are not the authorities of building codes or standards, but rather exist to promote the understanding and development of pre-stressed design, codes and best practices. In the UK, the Post-Tensioning Association fulfills this role.
Rules for the detailing of reinforcement and prestressing tendons are provided in Section 8 of the European standard EN 1992-2:2005 - Eurocode 2: Design of concrete structures - Concrete bridges: design and detailing rules.
In Australia the code of practice used to design reinforced and prestressed concrete is AS 3600-2009.

Famous quotes containing the words design, agencies and/or regulations:
“Teaching is the perpetual end and office of all things. Teaching, instruction is the main design that shines through the sky and earth.”
—Ralph Waldo Emerson (1803–1882)
“While it is generally agreed that the visible expressions and agencies are necessary instruments, civilization seems to depend far more fundamentally upon the moral and intellectual qualities of human beings—upon the spirit that animates mankind.”
—Mary Ritter Beard (1876–1958)
“The admission of Oriental immigrants who cannot be amalgamated with our people has been made the subject either of prohibitory clauses in our treaties and statutes or of strict administrative regulations secured by diplomatic negotiations. I sincerely hope that we may continue to minimize the evils likely to arise from such immigration without unnecessary friction and by mutual concessions between self-respecting governments.”
—William Howard Taft (1857–1930)
