scope:
This code sets forth requirements for the seismic evaluation and retrofit of concrete components of the seismicforce- resisting system of an existing building. These requirements apply to existing concrete components, retrofitted concrete components, and new concrete components. Provisions of this code do not apply to concrete-encased steel composite components.
Chapter 2 specifies data collection procedures for obtaining material properties and performing condition assessments. Chapter 3 provides general analysis and design requirements for concrete components. Chapters 4 through 9 provide modeling procedures, component strengths, acceptance criteria, and retrofit measures for cast-in-place and precast concrete moment frames, concrete frames with masonry infills, cast-in-place and precast concrete structural walls, and concrete-braced frames. Chapters 10 through 12 provide modeling procedures, strengths, acceptance criteria, and retrofit measures for concrete diaphragms and concrete foundation systems.
