Strength capacity of a story in low and mid-rise steel building considering the influence of horizontal load eccentricity is discussed in this paper. Firstly, the plastic-hinge numerical analysis taking into account the effect of torsion of members is described. Secondly, examples of 21 buildings sampled randomly from actual steel buildings and actual eccentricities were investigated. Then, the shapes of the strength interaction surfaces expressed in three axes of two directional lateral forces and torsion, of a story in these buildings, were obtained from the numerical analysis. On the other hand, an approximate equation of the strength surface was assumed, and its analytical values were compared with the above numerical values considering dispersion. Finaly, an empirical formula for the evaluation of lateral strength capacity reduction was derived taking the eccentricity into account. Further, the evaluation of equivarent strength associated with ductility under earthquake loading is presented.
