Has anyone seen any research of the use of steel in China's high rise blocks? I am interestered in the use of different types of steel - rebar/debar, structurals, mesh, flat products?

I am aware that China uses a lot of steel in its tall buildings, but has anyone seen any comments on how much per square metre or cubic metre in different building types - apartments, offices, hotels etc (I don't know the normal standard for measuring these things)?

I should add, maybe that, I write about steel, and so have some sort of professional interest in the subject.
