Question

★ It is noted that sometimes in an Earthquake short and tall structures remain unaffected while the medium height structures fall down . Explain why . ​

Answer 1

Answer:

According To Q :-

Tall High Rises:

Large structures or high rise buildings are more affected by long period, or slow shaking. For instance, an ocean liner will experience little disturbance by short waves in quick succession. Similarly, a sky  will sustain greater shaking by long period earthquake waves, than by the shorter waves.

Short Buildings Have Good Foundation that's why they reamin unaffected During an earthquake.

Answer 2

Hey mate !!

This happens because th naturela frequencies of the short structures happen to be higher and those of taller structure lower than the frequency of the seismicwaves. Due to it there is no resonant vibrations. ... The amplitude of oscillation of medium height structures becomes large and they collapse.

Hope this will helpful for you...
