Answer:
The building will vibrate around one particular frequency known as its natural, frequency, the building and ground share the building frequency its said to be in resonance.
Explanation:
- Resonance is the frequency of the system to oscillate with a greater velocity than the others as all buildings have a resonance period which is the number of seconds for a building to vibrate and the ground also shows the seismic resonance frequency, the mismatch of the resonance and the wave frequency. Thus taller buildings will be damaged more than shorter structures.
- <u>These forces create the lateral accelerations that scientists measure by the G-forces. The sudden movement creates enormous stresses for the building's structure, including the beams, the columns, and the walls and the floors, as well as the joints that hold them together. If that stress is large enough, the building can collapse.</u>
