How steady can a paper bridge be
NettetAbstract: The prediction of the flutter velocity as well as the response to turbulent wind has become a more and more important issue for flexible long-span bridges. For this reason flutter derivatives have to be measured in the wind tunnel with great accuracy and their dependence on the mean angle of attack, which is sometimes very strong, has to be … NettetCan you create a strong bridge with just a sheet of paper? Explore what makes the triangle a strong shape.

For the Tacoma Narrows Bridge, the diagonal ties did inhibit this mode at first but they be-came loosened (one broke, one cable clamp slipped) . The mode was then driven by auto-excitation forces of which the steady wind was the energy source .
