| Abstract: |
| The statistical characteristics of structural responses subjected to random load are described. The relation between correlation coefficient and coherent function is analyzed. According to these, the concept of correlation scale considering frequency characteristics of the structure and of the random load is developed to represent the characteristics of the random load. |
| Key words: random load,structural random response,correlation coefficient,coherent scale,structural dynamic analysis |
