Column Design Example - University of Alabama
richardson.eng.ua.eduframe. In a braced frame, some other element besides the columns resist sidesway, such as the shear walls in an elevator shaft. Where: k = effective length factor (assume equal to 1 for this example) lu = unbraced length = 12' r = radius of gyration = 0.3 h (ACI 10.10.1.2) r = 0.3 (18”) = 5.40” M2 is larger of two moments

On the other hand if no sides way bracing is provided to to an identical frame, the buckling will look like Figure 3.b. The column is in a situation similar to that of 2.d upside down, except that
