In the event of a major earthquake, large uncoupled axial and lateral forces can be developed in the columns of reinforced concrete (R/C) structures. The results of an analytical study on the effects of nonproportional axial load on the moment-curvature (M - ■ ) relationship for columns is presented. The results indicate that the moment capacity of R/C columns under uncoupled variations in axial load can be significantly smaller than a case in which the axial load is constant or when the variations are proportional to changes in moment. Thus, by recognizing this effect, the seismic design of R/C structures can be upgraded to resist complex loading histories that may occur under bi-axial (or 3-D) excitations of structures during earthquake ground motions. キーワード（英）： - 記事区分： - 区分 　　　委員会論文集
