Parametric analysis of carbon dioxide emissions associated with RC beams made with lightweight concrete under different design scenarios

These are the results from two parametric analyses involving reinforced lightweight concrete beams. Beams are continuous with two spans of equal length. The first set corresponds to downstand beams and the second set corresponds to flat beams (or wide-shallow beams). Over 3.25 million design scenarios are considered, obtaining the reduction in total load upon the supports, the flexural/longitudinal reinforcing steel consumption, the cement consumption and the equivalent carbon dioxide emissions associated with steel and cement consumption.

For the estimation of the tons of CO2 associated to each ton of steel, the following report was considered: https://www.worldsteel.org/en/dam/jcr:1b7492b1-15f5-401a-88f1-7ae488e0553f/SteelTalks%2520May%252020%20717%2021_Asa%2520Ekdahl.pdf

For the estimation of the tons of CO2 associated to each ton of cement, the following report was considered: https://docs.wbcsd.org/2009/06/CementIndustryEnergyAndCO2Performance.pdf

For the mix design of lightweight concrete, the method by Bogas and Gomes was considered (doi:10.1617/s11527-013-0029-1).

This dataset is associated to the paper "A parametric study to assess lightweight aggregate concrete for 2 future sustainable construction of reinforced concrete beams" by Vives, I., Varona, F.B., Tenza-Abril, A.J. and Pereiro-Barceló, J. published in the Special Issue "Complex System Modeling Methods Applied to Sustainable Development", in Sustainability, 2021 (in press, DOI pending).
