COLUMN is a computer program written to select cross sections for reinforced concrete columns by simulating the reasoning processes used by structural engineers. The logic used to select, evaluate, and, if required, modify a section is described. Provision is made for the designer to impose, a priori, any restriction on the concrete dimensions or reinforcement that may be desired. The program proportions and details tie dand spiral columns, braced or unbraced for either uniaxial or biaxial loading. Slenderness effects are considered using the moment magnifier method. The design of a tied column with examples of different user-imposed restrictions is included.
