Building Class Information Model (BCIM) package.

This package generates the information dataset representing the general characteristics of a building portfolio. It constitutes the first step of the BED framework pipeline (BCIM → BDIM → BNSM), producing realisations by sampling secondary building attributes from class-specific probability distributions and decision trees, conditioned on primary attributes (e.g., design class, number of storeys, lateral load factor).

Sampled attributes include geometry variables (storey heights, bay widths, floor layout), taxonomy (slab type, beam type, column section, material grades, construction quality), and masonry infill configuration. The main entry point is the BCIM class.

Example

>>> from bcim import BCIM
>>> model = BCIM()
>>> model.generate(design_class="eu_cdh", beta=0.1
                   num_storeys=4, sample_size=150)
>>> model.to_csv("path/to/output.csv")
