Abstract: Several aspects of nonslender (short) column limits are considered. Such limits, below which it is acceptable to ignore local second-order effects that may cause a maximum moment to develop between member ends, are generally ...

Abstract: The effective length approach for column stability evaluation has long played an important role in approximate methods of analysis. Methods for determination of effective lengths of compression members in frame systems are ...

Abstract: Approximate methods for determination of effective lengths of compression members in frame systems are normally based on rotational restraints defined through so-called joint stiffness ratios or

Abstract: When designing a reinforced concrete column, most codes of practice specify that second order effects must be taken into account when the column slenderness exceeds a lower limit, usually associated to a certain loss of ...

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 ...
