Through the push over analysis of two tall concrete buildings with different structure types the influence of second order effect on top drift and base overturning moment had been discussed in detail.

Abstract: the widening of gauge and the overturning of rail will effect the contact point and dynamic forces between wheel and rail.

And it is also similar of stability of overturning and derailing between titling train negotiating curve and traveling on level track under the effect of not so big crosswind.
