We discuss some nonlinear fourth order differential equations which describe oscillations in suspension bridges. We give strong theoretical and numerical evidence that solutions blow up in finite time with infinitely many wild oscillations. We exhibit an explicit example where this phenomenon occurs and we give a possible new explanation of the collapse of bridges.

Abstract

We discuss some nonlinear fourth order differential equations which describe oscillations in suspension bridges. We give strong theoretical and numerical evidence that solutions blow up in finite time with infinitely many wild oscillations. We exhibit an explicit example where this phenomenon occurs and we give a possible new explanation of the collapse of bridges.
