title: Universal Timber Slab: Simulated Multidisciplinary Performance Data for UTS Solid Timber Slab in Triangular Slab Bays at 1m Resolution

description: &lt;h2&gt;Overview&lt;/h2&gt;
&lt;p&gt;
This dataset includes preliminary results for &lt;strong&gt;Computational Design&lt;/strong&gt;, &lt;strong&gt;Structural Design&lt;/strong&gt;, &lt;strong&gt;Acoustics + Building Physics&lt;/strong&gt;, and &lt;strong&gt;Life Cycle Analysis&lt;/strong&gt; in relation to the default benchmark defined in the 
 &lt;a href="https://doi.org/10.18419/DARUS-5096" target="_blank"&gt;Slab Building Blocks dataset&lt;/a&gt;, "1. Triangular Slabs every 1.0m – Default".
&lt;/p&gt;

&lt;p&gt;
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.
&lt;/p&gt;

&lt;h2&gt;Data format&lt;/h2&gt;
&lt;p&gt;
This data format uses the &lt;a href="https://bhom.xyz/" target="_blank"&gt;BHoM framework&lt;/a&gt;.&lt;br&gt;
 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.&lt;br&gt;
All data is stored in &lt;strong&gt;JSON files&lt;/strong&gt; that contain BHoM objects.
Using SI units unless spefified differently.
&lt;/p&gt;

&lt;h2&gt;Data Structure&lt;/h2&gt;
&lt;p&gt;
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.
&lt;/p&gt;
&lt;p&gt;
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.
&lt;/p&gt;
&lt;h3&gt;&lt;strong&gt;Layers 1-3 - Computational Design, design and Geometry&lt;/strong&gt;&lt;/h3&gt;&lt;br&gt;
Defines the geometry and organization of the slabs. &lt;br&gt;
&lt;strong&gt;Input Datapoint:&lt;/strong&gt;&lt;br&gt;
Evert specimen defined in the default set at &lt;a href="https://doi.org/10.18419/DARUS-5096" target="_blank"&gt;Slab Building Blocks dataset&lt;/a&gt; conforming Layer 0. &lt;br&gt;
&lt;strong&gt;Output Datapoints:&lt;/strong&gt;&lt;br&gt;
&lt;ul&gt;
 &lt;li&gt;UTS.Slab: Slab general data container&lt;/li&gt;

&lt;/ul&gt;
&lt;h3&gt;Performance Solutions&lt;/h3&gt;
&lt;p&gt;
 Each bay of the slab is analyzed individually and different disciplines calculate different performance solutions based on the case and the previous information.
&lt;/p&gt;

&lt;h3&gt;&lt;strong&gt;Layer 4 - Slab Rerquirements&lt;/strong&gt;&lt;/h3&gt;&lt;br&gt;
