Abstract:
Simple approximate equations are presented for determining effective length and rigidity of columns for use in stability analysis and drift calculations of frames, including effect of cladding. The range of application of current design aids and the proposed equations is determined. Outside that range, the Grinter substitute frame is recommended and a simple, exact equation given for calculating its deflections. Stability under the action of eccentric lateral loads is treated using the story-stiffness approach. Tables of effective length factor for braced and sway frames are given.
