Abstract:
A new type of pivot element bar included piezoelectric stack material was proposed. Its applicability and suitability for the stability control of steel structure were also expressed. Basic mechanical performances of the piezoelectric spar element under cases of electromechanical coupling and electromechanical decoupling were considered with related structure mechanical theory. At the same time, influence of the length of the piezoelectric material included in the smart active spar element on static stability was quantitatively analyzed by numerical calculation. The results show that the ultimate bearing capacity will increase obviously if considered the electromechanical coupling effect; influence of the length of the piezoelectric material included in the smart active spar element on the stability behavior dose not linearly increase, only in a certain stiffness optimization, the control might be effective.
