In this paper, the mechanical behavior of wall girder-wide column assemblages with one-sided eccentricity is discussed from the experimental results and the ultimate strength of each test specimen is estimated using the previous proposed equations for predicting the shear strength of columns and joints under combined torsion and shear. The main conclusions are as following: 1) The failure mode of girder-column assemblages with eccentricity changes from flexural failure to shear failure. 2) When torsional strength of a joint is less than of a column due to small amount of transverse reinforcement, torsional failure controls behavior of the joints. 3) The ultimate strength of columns and joints should be calculated by considering the torsional stress and not effective width by proposed equation. 4) Proposed equation for predicting of shear strength of columns under combined torsion and shear does not reflect the contribution of column load and tensile column reinforcement ratio to the strength.
