Abstract:

The effects of PR-Type connections and loading arrangement on frame stability and the effective length factor of columns are evaluated for portal frames and three-story three-bay frames with rigid and flexible connections and member and joint loads, as the test cases. Based on second-order linear and non-linear analysis of these frames, suitable conclusions are drawn regarding the choice of K-factors.
