Input file for a n-storey building

plan_to_input_file_several_storeys.RmdBefore starting
We assume that you have read and successfully model the single-storey building in our vignette From the architect’s plan to the input file of floodam.building. If you have not yet done it, now it is the best time to do so.
Modelling a two-storey building from scratch
To do this model we count on the information displayed in the plans and table below. You have the plan of the house, a focus over each type of opening and a table summarizing key information. As an extra, we also include three perspective views so you can have a very clear idea of the building.
PLANS
MATERIALS & INFORMATION
| structural group | type of element | material | other information |
|---|---|---|---|
| ceiling | ceiling | concrete | ceiling made of concrete withe cellular plastic insulation and a paint coating |
| floor | floor | concrete | floor covered of glued tiling and wood coverstrips; ground level = street level |
| wall | load bearing wall | concrete | single layer render |
| wall | lining | polyplac | vegetal insulation, paint coating and tile baseboard. Interior face of external walls |
| wall | partition | placostil | paint coating and tile baseboard. Wall used to separate rooms |
| opening | window | pvc | solid PVC shutter |
| opening | interior door | alveolar door with wooden frame | |
| opening | exterior door | solid wood | |
| building | building | main use: dwelling. Thickness of load-bearing walls = 0.3m / Thickness of non-load-bearing walls = 0.1m |
As you can see, we are adding a basement to our single-storey building from the vignette From the architect’s plan to the input file of floodam.building, so we will not repeat the whole process. Instead we will focus on the additions and modifications to the input file to successfully add a storey.
The first thing that you should do in addition to what you have already done in the vignette From the architect’s plan to the input file of floodam.building is to calculate the coordinates of the basement. As you can see in the perspective views of the building, the basement is a single-room space located bellow the two rooms that work as main entrance of the house and the back room. In the figure below you can see the coordinates of this new room, labeled as room 5.
Once you have the coordinates of the new storey, it is time to introduce them in your input file. As we did in the vignette From the architect’s plan to the input file of floodam.building, we will provide the code chunks in both XML and YAML languages.
The first modification you should do to the single-storey building input file is to rename both the storey and external_wall in the building block. In our case, storey is renamed as storey_groundfloor and external_wall as external_wall_groundfloor. The reason behind is fairly intuitive: each storey in the input file is treated as a block with its own features and XYZ disposition. To avoid errors, labels should be different.
Once storey and external_wall are renamed, you can add your new storey. As you can see in the XML and YAML code chunks below, the way to introduce your new storey is the same as the one you already know from the vignette From the architect’s plan to the input file of floodam.building:
- You “open” your new storey block. In our example we have chosen to call it storey_basement
- you provide the general features of this new storey: height at which the storey is located in relation to the ground level (H), height of the storey (height) and name.
- you provide the sub-blocks dedicated to the external wall and room(s). Please pay attention to the names used in the example.
