Serial Information: Transactions of the American Society of Civil Engineers, 1961, Vol. 126, Issue 2, Pg. 929-951

Document Type: Journal Paper


Buckling strength of pinned-base rigid frame is considerably lower than that of identical fixed-base frame; in United States, however, pinned column bases are preferred for economical reasons; paper shows that rotational restraint offered by commonly used pinned column bases is sufficient to increase buckling strength of these frames to almost that of identical fixed-base rigid frames.
