An engineer is building a new steel skyscraper in a area with a lot of Earthquakes, Compare two systems (fixed based system and base isolated system) and choose which one would be better.

Explanation:

Fixed based system:-

A fixed-base building (built directly on the ground) will move with an earthquake’s motion and can sustain extensive damage as a result. 

Base isolated system:-

A base isolation system is a method of seismic protection where the structure (superstructure) is separated from the base (foundation or substructure).

Hence,

A base isolated system is much more better in a area where there are a lot of earthquakes.

yes? sounds right, but you didn’t ask a question.
