Nam,
The ASCE 24-05 was written primarily for structures with regard to human occupancy as opposed to industrial structures. And what you are describing is an industrial structure. I don't think that section 1.5.2 would apply to an industrial structure. Section 4.4 may be more applicable.
Taking the ASCE 24-05 at face value would infer that you have a Category II structure that should have the lowest level at the BFE. In the US, we have DFE's defined. I don't know if the DFE is defined in Vietnam. A hydrologist can calculate the BFE.
As this is an industrial structure, I would pose the question as to the effect a given flood would have. There are elements of a coal-fired power plant that could flood with minimal effect and could be constructed below the BFE. There are other elements in a power plant that should be elevated above the BFE because of the adverse consequences. I definately would not want the turbines, or any critical equipment to be below the BFE.
Regards,
Harold Sprague
