- Reinforced concrete special moment frames are used as part of seismic force-resisting systems in buildings that are designed to resist earthquakes. Beams, columns, and beam-column joints in moment frames are proportioned and detailed to resist flexural, axial, and shearing actions that result as a building sways through multiple displacement cycles during strong earthquake ground shaking. Special proportioning and detailing requirements result in a frame capable of resisting strong earthquake shaking without significant loss of stiffness or strength. These moment-resisting frames are called Special Moment Frames because of these additional requirements, which improve the seismic resistance in comparison with less stringently detailed Intermediate and Ordinary Moment Frames. This guide is written mainly to clarify requirements of the Building Code, but it also introduces other guides such as ACI 352R-02 and it presents other recommendations for good design and construction practices. This guide is written to clearly differentiate between Building Code requirements and other recommendations.
