Chapter 9: Column Analysis and Design

Short columns fail by crushing at very high stress levels that are above the elastic limit of the column material. Compressive stress for short columns is based on the basic stress equation developed at the beginning of Chapter 5. • If the load and column size (i.e. cross-sectional area) are known, the
