Study on the Influence of Different Structural Systems and Materials on the Structural Cost of Super Tall Buildings
This paper takes a complex building in Guiyang,Guizhou Province as an example to study the impact of structural system and struc-tural materials on the structural economy of super tall buildings.The results show that in terms of structural system,the single cost of the frame core tube is the lowest,934 yuan/m2,and the single cost of the tube-in-tube structure system increases by 39.8%.The single cost of frame-tube structure system increased by 53.7%.In terms of structural materials,the single cost of ordinary reinforced concrete is the lowest,1 187.2 yuan/m2,followed by shaped steel concrete,1 481.4 yuan/m2,and the highest is concrete-filled steel tube,1 901.1 yuan/m2.Con-sidering the mechanical properties and economic benefits of steel reinforced concrete,the property value of steel reinforced concrete is higher.Therefore,it is finally determined that the structural system is the frame-core tube structural system,and the material type is steel reinforced con-crete.
