An extensive computer study of long column action in frames is summarized for both unbraced and braced building frames. This summary paper (1) indicates the weakness of the R-method in caring for column buckling in certain frames subject to sidesway, (2) compares the accuracy of the moment magnifier and R-methods in this and other situations, and (3) gives the background for the modified R equations mentioned as alternates in the explanation of changes of the Building Code.
