ᐅ Structural engineering for gym equipment on the upper floor

Hello,

Is the use of the following exercise equipment uncritical for the structural integrity or the screed with underfloor heating in the upper floor of a timber frame house (built in 2024):

• Mini trampoline used by an adult weighing 75 kg (165 lbs), the trampoline surface area is approximately 0.7 m2 (7.5 sq ft)
• Spinning bike, total weight of bike and user approximately 160 kg (353 lbs), the area over which the feet of the spinning bike distribute the load is about 0.4 m2 (4.3 sq ft) (1 m (3.3 ft) long, 40 cm (16 inches) wide)

My main concerns are because the load from jumping on the trampoline is higher than the static body weight and the ceiling structure and screed experience dynamic loading and unloading during jumping. Pedaling on the spinning bike might also cause vibrations that could affect the ceiling structure and the screed, in addition to the high weight.

This inquiry is not about the floor covering or noise development.

Yes, no problem... Just imagine you’re having a party and 10 people are jumping at the same time on the upper floor. Do you really think your house will collapse?

Have you asked this question somewhere else already? It sounds familiar – you won’t get different answers here.

No benches.
1. The trampoline actually reduces the impact compared to jumping directly on the ground because the force is distributed over a larger area and the springs absorb the shock.
2. The bike spreads the load over 0.4 m2 (4.3 ft2), while a somewhat heavy person standing on one leg only applies pressure on 0.04 m2 (0.43 ft2). This makes the wooden beam ceiling seem quite relaxed.
