However, for some particular asymmetric structural configurations which are usually found in regions of low seismicity, such assumption might not lead to a conservative design. In this paper, a simplified one-story single-wall-frame structural model was adopted to study the effects of the torsional stiffness/resistance of the wall on the overall seismic response of the model. It is found that the torsional resistance of the wall can be substantially mobilized due to the large rotational displacement under ground motions. Simultaneously, the shear resistance of the wall can also be utilized because of the dynamic effect due to the rotary inertia of the mass. As a result, the interaction of shear and torque of the wall should be considered. It is also shown that this special structural system may actually fail under the combined shear-torsion loadings, in which the system is considered to be safe when the torsion stiffness/resistance of the wall is neglected. Moreover, the exclusion of the torsional resistance of the wall does not always lead to a conservative estimation of its shear demand. In some cases, the consideration of the wall torsion stiffness/resistance considerably reduces the torsional twist of the structural system.
