| Abstract: |
| The finite element analysis is used to analyse stability of trapezoidal frames of steel radial gates in reservoirs, hydroelectric power stations, etc. The elastic resistance of the side seal rubbers and unit stiffness ratio for girder to column are considered in this study. Results are expressed in terms of the effective length factors and the critical load of trapezoidal frame column in radial gates. |
