Nonlinear dynamics of cable nets - An engineering course
0 likes15 views
This document discusses the nonlinear dynamics of cable nets. It explores hidden resonant phenomena that can be detected through frequency response curves. An example is given of applying these concepts to the design of a cable net roof, showing how engineers can use nonlinear dynamics principles from nature to create strong yet elegant structural solutions.
