🏢 Structural Loading Analysis Safe for standard residential floors

Standard modern home construction supports 30–40 lbs/ft² uniform live load. Concentrated aquarium loads under 500 lbs can sit anywhere; tanks above 500 lbs (55+ gal) should ideally be placed perpendicular to structural floor joists and against a load-bearing wall.
