RC Element Analysis and Design Program
The design and construction of reinforced concrete buildings is controlled by the Building Code Requirements for Structural Concrete (ACI 318-11) of the American Concrete Institute (ACI) . The use of the term code in this text refers to the ACI Code unless otherwise stipulated. The code is revised, updated, and reissued on a 3-year cycle. The
code itself has no legal status. It has been incorporated into the building codes of almost all states and municipalities
throughout the United States, however. When so incorporated, it has official sanction, becomes a legal document, and
is part of the law controlling reinforced concrete design and construction in a particular area.
Therefore, tensile reinforcement must be embedded in the concrete to overcome this deficiency. In the United
States, this reinforcement is in the form of steel reinforcing bars or welded wire reinforcing composed of steel wire. In
addition, reinforcing in the form of structural steel shapes, steel pipe, steel tubing, and high-strength steel tendons is
permitted by the ACI Code.
