Excuse me, experts, how many kilograms of steel bars are used per square meter of construction area?

Multi-story frame: steel bar 38-42kg/m? .

Small high-rise building 1 1- 12 floor: 50-52kg/m steel bar? .

High-rise 17- 18 Floor: 54-60 kg/m steel bar? .

High-rise 30-story H = 94m: 65-75kg/m steel bar? .

H = 90m on 28th floor of high-rise serviced apartment: 65-70kg/m steel bar? . The spacing of bending moment reinforcement φ 8 is 150mm, and the spacing of distribution reinforcement φ 6.5 is 200mm.
