Abstract

The geometric nonlinearities in elastic nonsway frames are examined and used to review the rationale and accuracy of the ACI slender column design method. The use of nonsway effective length factors to account for effects of end restraints, and the assumptions of idealized end restraints in the conventional alinement chart for effective length factors are investigated. The discussion is also applicable to the moment magnifier portion of the AISC column interaction equation.
