The ways in which a building can be designed to eliminate the occurrence of resonance include:

1. Change the type of building materials: Different materials have different natural frequencies. By changing the materials used in the construction, the natural frequency of the building can be altered, thus avoiding resonance with the frequency of external forces such as wind or earthquakes.

2. Change the total weight of the building: The total weight of a building affects its natural frequency. By changing the weight, the natural frequency can be adjusted to avoid resonance.

3. Change the degree of attachment to the foundation: The way a building is attached to its foundation can affect how vibrations are transferred and absorbed. A stronger attachment can help reduce the risk of resonance.

4. Add mass to the upper floors: Adding mass to the upper floors can change the distribution of weight in the building, which can alter the building's natural frequency and help avoid resonance.

Changing the height of the building may not necessarily eliminate the occurrence of resonance. The height can affect the natural frequency of the building, but it's not a guaranteed method to eliminate resonance as it also depends on other factors like material, weight distribution, and attachment to the foundation.
