Discrete Structures
This is an applied example which clarifies the theory explained in section 2.1 of this chapter. As compared to section 2.2, this time the structure has an unstable posticritical equilibrium path. The effects of imperfections for this type of structure is shown, and the concept of collapse load is introduced.
