The American Concrete Institute and the Post-Tensioning Institute expanded their partnership to increase efficiency for design of structural post-tensioned concrete structures.
The partnership formalizes efforts through the new joint ACI-PTI Committee 320, Post-Tensioned Structural Concrete Code. The committee will develop and maintain structural concrete code requirements unique to the design of post-tensioned concrete and complementary to ACI 318, “Building Code Requirements for Structural Concrete.”
“Post-tensioning as an application used in concrete design and construction allows for benefits such as design flexibility, materials reduction, and efficient constructability,” said Tony Johnson, executive director of the Post-Tensioning Institute. “The establishment of joint ACI-PTI Committee 320 will not only help expedite the adoption of post-tensioning provisions into the concrete building code, but it will also enhance usability for the design engineer by consolidating post-tensioning design provisions into one convenient document.”
