Comparative Study on Engineering Cost of Steel Structure,Concrete Beam and Slab and Prestressed Hollow Slab Structure
In order to compare and analyze the economy of different floor structures,this paper introduces the structural design scheme of steel structure,concrete beam slab and prestressed hollow slab,and compares and analyzes the material consumption and economic benefits of three kinds of floor structures.The results show that the cost of structural steel is 87.8%;The proportion of template cost is 2.7%;The concrete cost of beam and slab structure accounted for 34.4%;Template cost accounted for 21.6%;The cost ratio of prestressed tendons of beam and slab structure floor is 32.0%.The proportion of template cost is 3.6%.The final floor engineering cost is prestressed hollow slab<beam slab structure<steel truss,compared with the prestressed hollow slab square meter engineering cost,beam slab structure cost increased by 6.2%;The square meter engineering cost of steel truss is increased by 21.3%,so the application of prestressed hollow plates should be vigorously promoted in the future.
