6, high-rise serviced apartment 28th floor H=90 meters steel bar 65-70 kg/m * m? Concrete 0.38-0.42m * m * m/m * m.
According to the new standard, the statistical data of more than 60 projects are given.
For 8-degree and Class III venues: the frame is generally 65-70kg per square meter; Frame shear is generally 70-75 kg per square meter; Shear walls are generally 75-80 kilograms per square meter. For 8 degrees, the second-class site: the frame is generally 55-60 kg per square meter; Frame shear is generally 60-65 kg per square meter; Shear walls are generally 65-70 kilograms per square meter.
For 7 degrees and Class III venues: the frame is generally 55-60 kilograms per square meter; Frame shear is generally 60-65 kg per square meter; Shear walls are generally 65-70 kilograms per square meter. For 7 degrees, the second-class venue: the frame is generally 45-50 kg per square meter; Frame shear is generally 50-55 kg per square meter; Shear walls are generally 55-60 kilograms per square meter.
For 6 degrees, the second-class venue: the frame is generally 35-40 kg per square meter; Frame shear is generally 40-45 kg per square meter; Shear walls are generally 45-55 kilograms per square meter. For 6-degree and Class III venues: the frame is generally 40-45 kg per square meter; Frame shear is generally 45-55 kg per square meter; Shear walls are generally 50-60 kilograms per square meter. When bidding, you can use the content inside, the coefficient is * 1. 15.
Factors affecting the number of steel bars:
1, the content of concrete reinforcement should be discussed according to the structure type, height, presence of basement, etc.
2, the factory should also consider factors such as column spacing and production technology;
3. Of course, this is the average value, which mainly refers to the difference between the standard floor and the conversion floor;
4. It is related to the grade of steel bars, and there are fewer grade III steel bars;
This is just a general situation, but many times this figure can only be used as a reference. Each building also needs severe cramps;
6. After the implementation of the new Code for Design of Reinforced Concrete Structures, the amount of steel bars has greatly increased;
7. There are also gaps in the content of steel bars in the construction drawings of various design institutes.
