| Abstract: |
| This paper focuses on the item of structural parameters identification without input information. An aglorithm named as uniform load statistical average method is proposed and its procedure is described based on the charicteristic of pulsation wind on structure. To give the algorithm a solid basis, a theoretical certificate is given in the paper. Further numerical studies show that the proposed algorithm is highly efficent not only for noise free situation but also for noise included situation. The new idea given in the paper seems to supply a hopeful way for parameter identification with unknown input. |
