By using the finite-element software

the performance of structural mechanics

such as stiffness and strength etc.

of hoisting platform used for inner steeel barrel of chemney for 2×600 MW units in Nanjing Power Plant has been analysed

and a comparison with the result of real test being made.Results show that the change tendency of stress at corresponding points are identical as the load is increasing.The result of finite-element analysis can provide basis for smooth implementation of on-the-site hoisting work for inner steel barrel.
