The stability of the scaffold important, scaffolding, construction scaffolding, construction steel pipe scaffold
Scaffolding is our commonly used a medium construction tools, so the stability of the scaffold is very important. A structure or a portion of their 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. Usually will be based on the ideal mathematical model to study the stability of the theory is called buckling theory, based on the actual bar study consider the various factors related to the stability of the stability of the ultimate bearing capacity theory called the theory of crushing. Practical bar, component or structure damage occurred during use or as the loading test of the buckling load is called crushing load and ultimate bearing capacity. For simplicity, commonly used buckling load.
