• Analysis procedures and
acceptance criteria: follow the
PEER TBI Guidelines
• For this case study, we use
three suites of ground motions
and take the maximum value
• Selection and modification of
GM : Follow PEER GMSM
• The three GM represent
subduction, benioff and
background earthquake

Fundamental principle of base isolation: modify the response of the building so that the ground can move below the buildings without transmitting these motion into the building.
ASIA CONSTRUCT CONFERENCE 2013
The codes gives minimum design requirementsIt does not guarantee the building will not be damaged during earthquake
It does not protect the content from damage

� Loma Prieta 1989 – $7 Billion
� $450 Million per Second
� Northridge 1994 - $30 Billion
� $2 billion per second!
� Kobe 1995 - $150 - $200 Billion
� $7.5 billion per second!!
Earthquakes can be Catastrophic and Very Expensive
