Base Isolation Conventional Construction Practice assumes Fixed Base Structures The Dynamic Characteristics of Fixed Base Structures are determined by the general characteristics of the structural system The Designer can only slightly adjust those Dynamic Characteristics As a matter of fact, most common Building Structures have unfavorable Dynamic Characteristics that result in increased Seismic Response Earthquake Performance of Fixed Base Structures Conventional Fixed Base Structures can not be realistically designed to remain elastic in large seismic events (more so in regions of high seismicity) Common 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 Fixed Base Base Isolated Period Response Significantly Increase the Period of the Structure and the Damping so that the Response is Significantly Reduced Base Isolation in Buildings Original Structure Isolated Structure Isolation at foundation level Base Isolation in Buildings Isolator Components Between the Foundation and Superstructure An Isolation Interface is formed Base Isolation in Buildings Base Isolation in Buildings
