This paper presents an analytical study of the inelastic behavior of K-braced structures of steel when subjected to a strong earthquake motion. A 10-story structure designed by current code procedure is subjected to a horizontal ground motion 1.5 times the intensity of El Centre 1940 earthquake. Elasto-plastic type hysteresis behavior in bending is assumed for girders and columns with axial force effects included for the columns. The hysteresis model for the axially-loaded bracing members, considers tension yielding and elastic buckling with no energy dissipation in the postbuckling range. The effect of three different patterns of bracing (K, V and X) on the structure response is studied. The results for K-braced frames differ significantly from earlier results obtained by Nilforoushan (7) in which he used a more realistic post-buckling behavior of the bracing members in his hysteresis model. Thus it appears that post-buckling behavior is an important factor in predicting the behavior of a K-braced frame structure. A combination of the K- and V- pattern of bracing (the X-pattern) results in least ductility demand on girders and the bracing members. キーワード（英）： - 記事区分： - 区分 　　　委員会論文集
