Besides, it has the necessity to strengthen the longitudinal rigidity of the structures which has the outstanding features of one way load carrying characteristic.

This permits a high level of lateral rigidity on the one hand for optimum dynamism and driving safety, while offering a great degree of longitudinal flexibility on the other to improve ride comfort.

I found that the hinged ends and the varying rigidity can affect the values of moments and displacement very much. The values of transverse moments are almost equal with longitudinal moments.
