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:
“With wonderful art he grinds into paint for his picture all his moods and experiences, so that all his forces may be brought to the encounter. Apparently writing without a particular design or responsibility, setting down his soliloquies from time to time, taking advantage of all his humors, when at length the hour comes to declare himself, he puts down in plain English, without quotation marks, what he, Thomas Carlyle, is ready to defend in the face of the world.”
—Henry David Thoreau (1817–1862)
“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)
“If it were possible to make an accurate calculation of the evils which police regulations occasion, and of those which they prevent, the number of the former would, in all cases, exceed that of the latter.”
—Karl Wilhelm Von Humboldt (1767–1835)
