| Abstract: | The penalty element method was used to solve the coordinate problem among different elements. The self vibration characteristics of the powerhouse structure of the Three Gorges Hydropower Station were been studied in two design alternatives. The effect of the upper roof slabs, steel roof truss and crane beam on the self vibration characteristics of the powerhouse structure of the Three Gorges Hydropower Station was discussed. The effect of connecting ways between floor slab and downstream and upstream walls of powerhouse on the calculation results was demonstrated in the calculation model. |
