Cost and CO2 Emission Reduction Effects of a Partially Encased Composite Precast Concrete Beam
|Published in:||Advances in Civil Engineering, January 2020, v. 2020|
In order to study the performance of partially precast partially encased assembled composite beam (PPECB) in reducing costs and reducing carbon dioxide (CO₂) emissions, this paper obtained the bearing capacity of PPECBs by a static test. Considering the load conditions and beam height conditions as constraints, the steel-concrete composite beam (SCCB) and reinforced concrete beam (RCB) were optimized and designed based on the principle of fully utilizing the advantages of steel and concrete. On the basis of investigating the quantity of different materials, the cost and CO₂ emissions of the three different types of beams were analyzed. The cost and CO₂ emission of the PPECB are the lowest, and SCCBs have the highest cost and CO₂ emissions. This paper can provide reference for design choice and further research from the perspective of cost and CO₂ emission and lay a solid foundation for the realization of economic and environment-friendly buildings.
