| Abstract |
Numerical uncertainties of initial data can result in uncertainties of structural responses, such as an uncertain displacement. And as a tool which evaluates uncertainties of initial data or structural system responses, interval analysis is a technique which describes an uncertainty as a non-stochastic method. Numerical uncertainties of initial data are assumed as a tolerance error , and through a tree graph of initial data combination related with numerical uncertainties, we can product structural response data of uncertainties. The calculated results show that the method is effective. |
