Links to publications that cite or use the data: Please refer to the associated journal article 2. Recommended citation for this dataset: Please cite the associated journal article DATA & FILE OVERVIEW 1. File List: 01_EC_Shares.m 02_3D_EC.m 03_Min_EC.m 04_Sensitivity_MinThickness.m 05_FEA_Deflection.gh 06_Min_EC_Depth_Values.xlsx 2. Relationship between files: The MATLAB codes predominantly designt the reinforcement details and calculates embodied carbon. The GRASSHOPPER file contains the Parametric Finite Element Model. The files does not pass variables among them. 3. Additional related data collected that was not included in the current data package: While some of the MATLAB scripts and spreadsheets generated in the study are not included in this data package, all the relevant output of the paper can be generated by a) slightly varying the input variables of the provided scripts b) by replacing some part of the body with another part of the given scripts. ---------------------------------------------------------------------------- METHODOLOGICAL INFORMATION 1. Description of methods used for collection/generation of data: All the procedures, logic and flow charts are described in the paper. 2. Instrument- or software-specific information needed to interpret the data: MATLAB R2020b is used to develop the programme scripts in this dataset. Rhino 7, Grasshopper and SOFiSTiK FEA is used for parametric finite element model. The MATLAB codes use the function 'supersizeme.m' to improve graphical representations. The function can be found in : https://uk.mathworks.com/matlabcentral/fileexchange/67644-supersizeme ---------------------------------------------------------------------------- DATA-SPECIFIC INFORMATION FOR: 01_EC_Shares.m 1. Description: This MATLAB script produces graphs containing the variation of embodied carbon shares from concrete, flexural reinforcement, shear reinforcement, and columns with design slab depth for a given span and a grade of concrete. This is used to generate figure 4. 2. Variable list: CL - Column height (in m) ColX - Column size (in mm) ColY - Column size (in mm) hmin - Minimum considered slab depth (in mm) hmax - Maximum considered slab depth (in mm) SpanMin - Minimum span considered (in m) SpanMax - Maximum span considered (in m) fck - Characteristic compressive strength of concrete in slabs (in MPa) fsy - Characteristic yield strength of steel (in MPa) fckcol - Characteristic compressive strength of concrete in columns (in MPa) ecSlabCon - Embodied carbon coefficient of concrete in slabs (in kgCO2/kg) ecColumnCon - Embodied carbon coefficient of concrete in columns (in kgCO2/kg) ecSteel - Embodied carbon coefficient of steel (in kgCO2/kg) RFincrease - Ratio of Provided reinforcement to required reinforcement The above variables can be adjusted to recreate different cases. ---------------------------------------------------------------------------- DATA-SPECIFIC INFORMATION FOR: 02_3D_EC.m 1. Description: This MATLAB script produces graphs containing the 3D embodied carbon plots varying with column spacing and slab tickness. This was used to create Figure 5. 2. Variable list: Same as previous. ---------------------------------------------------------------------------- DATA-SPECIFIC INFORMATION FOR: 03_Min_EC.m 1. Description: This MATLAB script produces graphs containing minimum embodied carbon and the corresponding slab thickness fro a range of column spacings. This was used to create Figure 6(c) and 6(d). 2. Variable list: Same as previous. ---------------------------------------------------------------------------- DATA-SPECIFIC INFORMATION FOR: 04_Sensitivity_MinThickness.m 1. Description: This MATLAB script produces graphs describing the sensitivity of optimum designs to carbon coefficients. This was used to create Figure 12(a). 2. Variable list: Same as previous. ---------------------------------------------------------------------------- DATA-SPECIFIC INFORMATION FOR: 05_FEA_Deflection 1. Description: This Grasshopper script contains the parametric finite element model to estimate nonlinear long term deflection. This can be visualised in Rhino and can be processed with SOFiSTiK FEA Rhino Plugin. The text file parts connected to the programme are written in TEDDY language to acess the nonlinear analyses in SOFiSTiK. 2.
