Instability phenomenon of the scaffold structure according to their occurrence can be divided into: the scope of the whole structure or some of its instability, instability of individual components and component of local instability; And both can be divided into the in-plane and out-of-plane instability. Sometimes within the scope of the elastic buckling will not occur, and in the whole cross section to plastic elastic-plastic buckling occurred before, so can be divided into the elastic stability, elastic-plastic stability and plasticity and stability. Any kind of instability phenomenon is likely to make structure can't work effectively. At the same time taking into account all the direct solution of these problems will be very complicated, so on buckling strength and bearing capacity of the actual structure of the systematic analysis method still needs further research. Stability problems also can be divided into dynamic stability and static stability. The stability concept refers to the static stability. Dynamic stability can be according to the characteristics of energy expressed as: a system by external loading, under the condition of positive damping, the system potential energy and decay over time, the system's dynamic stability; In negative damping cases, the potential energy of system increases over time, the system is dynamic instability.
