2021 IBC SEAOC Structural/Seismic Design Manual, Volume 3: Examples for Concrete Buildings This series provides a step-by-step approach to applying the structural provisions of the 2021 International Building Code and referenced standards. Volume 3 contains code application examples of concrete construction. Moment frames, braced frames, and shear wall construction are analyzed. Volume 3 details sample structures containing concrete moment frames or shear walls, diaphragm, and pile design, including: Reinforced Concrete Wall Reinforced Concrete Wall with Coupling Beams Reinforced Concrete Special Moment Frame Reinforced Concrete Parking Garage Pile Foundation Pile Foundation at SMRF Design of Concrete Diaphragm and Collector, including Alternate Method Concrete Coupling Beam An excellent reference and study guide for the NCEES Structural Exam, this manual is an invaluable resource for civil and structural engineers, architects, academics, and students.
