Analysis of the Influence of Building Height on the Engineering Cost of Frame-core Tube Structure
In order to analyze the influence of building height on the cost of frame-core tube structure,the paper mainly analyzes the relation-ship between the amount of building materials and the cost of frame-core tube and the building height(100,200,300,400 m)under different fortification intensity(5.5°,7.5°).The results show that when the fortification intensity is 5.5°,the increasing slope of the total cost-con-struction height curve is1.11 yuan/m3.When the fortification intensity is7.5°,the increase slope of the total cost-construction height curve is 1.49 yuan/m3.The steel cost of 7.5° fortified intensity is 55%～84%higher than that of 5.5° fortified intensity,the concrete cost of 7.5° fortified intensity is20%～24%higher than that of 5.5° fortified intensity,and the total engineering cost of 7.5° fortified intensity is47%～72%higher than that of 5.5° fortified intensity.
