Reinforced Concrete Columns and Walls

A beam gives warning before it fails; a column gives none. And the failure of one column in a lower storey does not stop there — everything above it comes down. So a column is designed with a lower factor and a wider margin, and things are checked in it that are checked nowhere else: slenderness, interaction, and the detail that holds the bars in place. The vertical load path with tributary area and live load reduction, short columns in axial compression, the axial-moment interaction diagram and the balanced point, slenderness and moment magnification, ties splices and detailing, structural walls with in-plane shear and boundary elements, then the column to footing interface in bearing dowels and punching shear, and reviewing a column schedule. 10 fully worked examples, every number checked.
