NOISE & VIBRATION ISOLATION OF GYMS IN HIGH RISE BUILDINGS

Healthier living, exercising, training or body building is currently a common trend in many countries.Training before or after work is a common practice nowadays. Nonstop gyms are becoming popular as they provide flexibility to customers to exercise even after night shifts. Fitness centres being close from working areas find greater commercial success. Gyms located in High rise buildings are becoming increasingly popular.

Running, weight lifting, hard exercises, spinning mixed with loud music, make gyms often an unwanted neighbour.

When massive concrete slabs can not be used on the building, the degree of required transmission loss on the suspended floor becomes relevant. For this purpose the stiffness of the floating floor anti vibration mounts play an important role.

Althought a concept of a box in box type is always an advisable soundproofing strategy, on this article we will concentrate on a recent work done in a high rise building in Panama city downtown.

The concept was to make a grid of 1,05 x 0,85m where high deflection Vibrabsorber+Sylomer® spring mounts with a Sylomer base were installed on the intersection of the grid as shown below

For the calculation it was considered that the elastic energy of the spring is equal to the potential energy of the weight being dropped.

The elastic Energy is calculated on the basis of the stiffness and the amount of springs and the margin of the deformation of the spring (Max static deflection of 30mm)

Elastic energy = ½ * k * x^2

With the formula of the potential energy we calculated the maximum weight that could be absorbed by the springs when dropped from 0,5m height.

Potential energy = m*g*h

The floor was divided in 4 different zones, which were studied independently.

Zone Lenght Width Height of the floating slab Weight of the floating slab Amount of springs Load per mount Reference Stiffness (N/m) Deflection (mm) Margin to max defl (mm) Energy = 1/2·kx^2 Height (m) Maximum mass (Kg)

In order to avoid the stiffening due to the trapped air within the cavity of the floating slab air evacuation areas were strategically placed on the floating slab.
