Science Based Seismic Design (SBSD)

Seismic design procedures have varied through the years. Energy, displacement, and strength have all been proposed as the design parameter of interest. The development of analytical tools which are capable of predicting the inelastic response of non-linear systems allows us to adopt a more scientific approach to creating a structure which will meet performance objectives. The confirmation of analysis procedures on earthquake simulators will continue to provide confidence in our ability to attain performance objectives. The Tall Buildings Initiative (LATBS) as proposed by the Los Angeles Tall Buildings Structural Design Council represents a first step in this direction. A similar design proposal has been suggested by the Pacific Earthquake Engineering Research Center (PEER); it is currently being tested analytically. The objective of this effort is to describe the philosophical basis for SBSD and how it can be simply and reliably introduced into our seismic design vocabulary.
