Conventional Construction Practice assumes Fixed Base Structures

lThe Dynamic Characteristics of Fixed Base Structures are determined by the general characteristics of the  structural system

lThe Designer can only slightly adjust those Dynamic Characteristics

lAs a matter of fact, most common Building Structures have unfavorable Dynamic Characteristics that result in increased Seismic Response

Earthquake Performance of Fixed Base Structures

lConventional Fixed Base Structures can not be realistically designed to remain elastic in large seismic events (more so in regions of high seismicity)

lCommon practice is to design them so that they experience damage in a controlled manner and have large inelastic displacements potential

Unconventional Earthquake Protective Systems\

Base Isolation is the most common System

The Concept of Base Isolation

Significantly Increase the Period of the Structure and the Damping so that the Response is Significantly Reduced

Base Isolation in Buildings

Isolator Components Between the Foundation and Superstructure

How exactly does Base Isolation Work?

Most types of Isolators exhibit nonlinear behavior

Lengthening of the Structure’s Period and increased Damping that result in a large scale decrease of the Seismic Response

Force – Displacement Relationship at the Isolation Interface

Response of Base Isolated Buildings versus Fixed Base Response

Reduced Superstructure Deformations for Base Isolated Structure

Most Common Types of Isolation Components (Isolators)

Elastomeric Isolators
– Lead Core Rubber Bearings

Sliding Isolators
– Friction Pendulum System
