| Abstract: | In this paper simplify compute method of platform basal frequency is given, in consideration of effects of shear,bend and rotary inertia in equation. Anather effects, such as shape change of jacket, rotary inertia and concentrate mass change of platform, are determined by use of revise coefficent. |
| Keywords: | rotary inertia effects of shear combinations rigid |
