建築基準法施行令 第八十五条（積載荷重）

Urban Farm DB summary

Article 85 of the Building Standards Act Enforcement Order requires live loads on each part of a building to be calculated according to actual conditions in principle, but allows using tabulated values multiplied by floor area for listed room types. Rooftop plazas and balconies follow the same category-(1) values as residential rooms (1,800 N/sqm for floor structural calculation, 1,300 N/sqm for girders/columns/foundations, 600 N/sqm for seismic force), but for buildings used as schools or department stores, the higher category-(4) values apply (2,900/2,400/1,300 N/sqm).

Only numbers and their conditions are stored, as structured data — never the source's own sentences. Metric and condition names stay in English, as coded.
