Research on Life Cycle Carbon Emissions Based on Steel Structure Schemes of Prefabricated Buildings
In order to study the life cycle carbon emission differences of different steel structure schemes for fabricated building,modular steel structure and pure steel frame structure schemes are designed respectively for a practical project,and the life cycle carbon emissions of the two schemes are analyzed quantitatively based on the theory of life cycle assessment.It is found that the total carbon emission of the steel modular structure scheme is 10.61%higher than that of the pure frame structure of the same scale.The operation and building material production periods account for the largest two proportions of the carbon emissions of the two structure schemes,which reach 73.33%and 81.11%respectively.The recycling of the modules and high efficiency of construction of the modular steel structure scheme can effectively reduce carbon emissions.Finally,the carbon reduction strategies of steel structure buildings are put forward to provide references for low-carbon building designs.
