Analysis of the Influence of Beam and Slab Layout on the Cost of Basement Roof
In order to analyze the influence of beam slab structure on the basement roof economy,this paper takes a construction project as an example to compare and analyze the material consumption and total cost of basement roof under four structural forms:main beam slab,cross main and secondary beam slab,beamless slab and prestressed hollow slab.The results show that the proportion of construction materials cost per unit area is the highest and the proportion of machinery cost is the lowest.The order of labor cost is cross main and secondary beam plate>main beam plate>prestressed hollow plate>no beam plate.The order of material cost is the main beam plate>cross main and secondary beam plate>beamless plate>prestressed hollow plate;The order of mechanical cost is prestressed hollow plate>cross main and secondary beam plate>main beam plate>no beam plate.Therefore,based on the principle of optimal engineering cost,the basement roof structure a-dopted in this project is the roof layout structure type without beam plate.
