The dynamic analysis and structure optimisation for factory building of Three Gorges Power Station

摘要

A. Proceeding from the results of optimization of dynamic analysis, the upstream and downstream solid wall scheme was adopted, which have many advantages. The wall should be thickened to 2.0m.b. Through the resonance checking, the dynamic deflection and stresses calculating, it could be said that the structure of the factory building is safe.c. The air shroud and the floor-slab in the generator floor should be thickened in order to improve the dynamic and static strength.
