Flexible buildings (made of wood or steel) have a resonant period than a stiffer building (one of brick or concrete).

Longer

Explanation:

All structures have a characteristic period, or reverberation, which is the quantity of seconds it takes for the structure to normally vibrate to and fro. The ground likewise has a particular full recurrence. Hard bedrock has higher frequencies milder silt. In the event that the time of ground movement coordinates the normal reverberation of a structure, it will experience the biggest motions conceivable and endure the best harm. Wood and steel are more favored in risky areas.High rises wherever should be strengthened to withstand solid powers from high breezes, however in tremor zones, there are extra contemplation.
