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
