Floor Vibrations

Analyze floor vibrations from human activities and calculate resonance frequencies. Includes wooden beam floors and concrete floors on various ground materials.

Material/Structure	Span/Type	Resonance Frequency (Hz)
Wooden Beam Floor	3 m joist span	12
Wooden Beam Floor	6 m joist span	9
Wooden Beam Floor	9 m joist span	7
Wooden Beam Floor	12 m joist span	6
Wooden Beam Floor	18 m joist span	5
Concrete Floor - Sand	Ground foundation	20
Concrete Floor - Clay (wet)	Ground foundation	15
Concrete Floor - Clay (hard)	Ground foundation	30
Concrete Floor - Gravel	Ground foundation	22
Concrete Floor - Limestone	Ground foundation	40
Concrete Floor - Solid rock	Ground foundation	45
