| Abstract: |
| The values of load assessment reference periods of existing hydraulic steel gate structures are determined by using an analogical method. The static water force is taken as an example in the calculation of statistical parameters in the load assessment reference period. And the variation of the reliability index of the structural member being damaged in bending in a continuous service period is discussed. |
| Key words: design reference period,design service period,assessment reference period,continuous service period,load,reliability index,gate |
