Color room steel structure analysis of causes of instability and instability

Rare color Board room steel structure classification of three of instability, the distinction between structural instability type of property is very important, because correct judgment will it be possible to accurately estimate the stability bearing capacity of structure.

1 first class stability, also known as the stability of equilibrium bifurcation (also known as bifurcation buckling) of perfect straight rod under axial compression buckling and perfect flat surface compression buckling when you fall into this category;

2 second stability problem, also known as non-stability of equilibrium bifurcation problem (also called the maximum point instability) eccentric compression members made of construction steel, plastic develops to a certain level of ability to lose stability, fall into this category;

3 jump more instability is different from the above two types, neither equilibrium bifurcation point and non-extreme points, jumping to another equilibrium State after the loss of equilibrium.
