| Abstract |
According to IEA (International Energy Agency), carbon dioxide (CO2) emissions due to the energy consumed by buildings are accounted for about 24% of the total CO2 emissions. Extensive studies related with reducing CO2 emissions have been carried out after the 2000s. For the environmentally sound and sustainable development, it is considerably important to design buildings considering CO2 emissions in the conceptual design stage. Especially, unlike the steel structures, CO2 emissions are different for each material (e.g. steel and concrete) used in the reinforced concrete (RC) structure. So, the volumetric ratio occupied by each material will have an effect on CO2 emissions. In other words, it is necessary to know the CO2 emissions relationship between two materials in order to reduce CO2 emissions of RC structures. This study is on target to investigate CO2 emissions of steel and concrete depending on material strengths and loading conditions in RC columns. |
