Computer Study of Long Columns in Frames.

An extensive computer study of long column action in frames is summarized for both unbraced and braced building frames. This summary paper (I) indicates the weakness of the /-method in car-ing for column buckling in certain frames subject to sidesway, (2) compares the accuracy of the moment magnifier and /{-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.
