Influence of Partial Base Fixity on Frame Stability
The buckling strength of a pinned-base rigid frame is considerably lower than that of an identical fixed-base frame. In current design practice in the United States, however, pinned column bases are specified for most structures because the construction of suitable foundations for fixed bases usually increases the over-all cost. It is shown that the rotational restraint offered by commonly used “pinned” column bases is sufficient to increase the buckling strength of these frames to almost that of identical fixed-base rigid frames.
