Overview

This dataset includes preliminary results for Computational Design, Structural Design, Acoustics + Building Physics, and Life Cycle Analysis in relation to the default benchmark defined in the Slab Building Blocks dataset, "1. Triangular Slabs every 1.0m – Default".

The slabs included were computed through various disciplinary layers, capturing performance data across multiple domains. The results are intended to serve as a baseline for further research and comparative analysis.

Data format

This data format uses the BHoM framework. It is possible to load the dataset with the core version of BHoM, even though a UTS BHoM Toolkit was used to organize the data. This ensures compatibility with the computational design method and future developments. All data is stored in JSON files that contain BHoM objects. Using SI units unless spefified differently.

Data Structure

Following the structure of BHoM and JSON files, the data is organized in a nested structure. For each design geometry, a "Performance" section contains multiple "PerformanceSolutions" per bay. Thus, each disciplinary layer can autonomously generate different solutions, while a versioning system enables them to refer to and align with outputs from other layers, maintaining links between interconnected results.

Below you can find the description of the relevant data points that are the core results to measure and reproduce the dataset layer by layer.

Layers 1-3 - Computational Design, design and Geometry Defines the geometry and organization of the slabs. Input Datapoint: Evert specimen defined in the default set at Slab Building Blocks dataset conforming Layer 0. Output Datapoints:

File naming Name example: Slab_2_3_5_LT1_CR2_GC5

Name parameters: Slab_A_B_C_LT#_CR#_GC#

Each parameter is indexed with an integer to keep the names simple.

-Triangle Edge Length (A_B_C) = refers to the triangle edges selection parameter in our sample domain. The range for this data set was 4 to 12 meters.. -Column Head Radii (CR): CR2 = 0.65m -Lamella Thickness (LT): LT1 = 0.03m (with max 200x Bend Radius) -Group Count Cap (GC): 5 max. The amount of lamella groups (packages) was capped at 5.

This data set is not related to a publication at the moment of release, but we forsee cites and references in the upcoming year. It is initially published due to funding requirements.
