<p>The coupling effect of bendig moments and shear forces on the materially nonlinear behavior of the Timoshenko beam model is usually ignored in the conventional seismic analysis. This paper invetigate the validity and accuracy of ignoring the above coupling effects. As the result of this investigation, it is revealed that there exist cases in actural structures where the coupling effect considerably reduces the strength and ductility of structures. In these cases, the coupling effect have to be inevitably considered. Therefore, the corresponding cases are demonstrated in terms of structural parameter ranges. The validity of the above parameter range is examined by the time history response analysis on elevated-girder bridge model under bi-directional seismic accelerations.</p>
