While China does have its own building design codes, I can only assume that it is not fundamentally different from the generally accepted design practices for structural steel elsewhere in the world. Also, at least early-on, many of China's new skyscrapers were designed by American firms. I would suggest that they would use their details where ever possible.
Skyscrapers (in the US and elsewhere) can be made to use no more than 30 to 50 lbs of structural steel for each square-foot of floor area. If a building has 1 msf, then expect 15,000 to 25,000 tons of steel. For the current US market, $3,000 to $5,000 per ton is not unreasonable (supply, fabricate, deliver, and possibly erected).
Here's a question for you - what is "debar"?
