Abstract:A simplified method to calculate the moment mag-nification factor and the critical buckling load for a laterally unsupported story of a building is discussed. The method is a hand calculation technique which has nearly the same results as a computerized P A method. The method is a substitute for the effective length method. A practical designer% definition of a braced frame is given. A practical designer's definition of frame instability is given. Several design examples are given toillustrate the application of the procedures.
