The objective of this study is to clarify the influence of the bracing stiffness and the bracing strength on the post buckling behavior of compression members with lateral bracing. In order to do this, elastic-plastic analyses of compression members with a lateral bracing were performed, considering the yielding of the lateral bracing. The obtained results are summarized as follows: 1)The maximum bracing force is not the bracing force at which buckling occurred. The maximum bracing force occurred in post buckling range. Therefore, if the bracing strength is more than bracing force at the buckling and smaller than the maximum bracing force, then lateral bracing yields in post buckling range. 2)When the bracing strength is more than the maximum bracing force, lateral bracing does not yield. And the post buckling load is nearly equal to the basic strength regardless of the bracing stiffness.
