OUTLINE
1. BACKGROUND
More and more super high-rise buildings are designed and
constructed to challenge the limitation of human ambitious, and this
skyscrapers become the landmarks of a cities or a regions.
In China500m
600m
1. BACKGROUND
But, how about a super-high rise building’s performances?
Does it perform according to original design?
If it has some defects, what will happen? And
What we can do?
------- Monitoring on structural responses is an efficient
way to help us to understand the structural performance
and then control the development.
-------- Now, It is also a modern solution for seismic
mitigation.
