Abstract
As the earthquake engineering community continues to embrace Performance-Based Seismic Design (PBSD) design procedures such as Direct-Displacement Based Design (DDBD) continue to evolve such that practicing engineers have the tools needed to accomplish the goals of PBSD. The DDBD approach has been developed over the last 25 years building upon the work of numerous researchers at multiple universities. During this presentation, following a brief motivation for the need for DDBD, the salient features of the design approach will be presented by describing the approach for SDOF systems and MDOF systems such as multi-span bridges and multistorey buildings. Sample designs for each case will be discussed, along with representative response verifications via nonlinear time history analysis.

Short Bio: Mervyn Kowalsky is the Christopher W. Clark Distinguished Professor of Structural Engineering in the Department of Civil, Construction, and Environmental Engineering at North Carolina State University. He is a registered Professional Engineer in North Carolina and an active member of several national and international committees on Performance Based Seismic Design.
Dr. Kowalsky is currently serving on the editorial board of Earthquake Spectra (the journal of the Earthquake Engineering Research Institute), and has received the ACI Structural Research Award for his work on the seismic behavior of lightweight concrete bridges, the ACI Wason Medal for Materials Research for his work on the “Buckled Bar Tension Test”, and the ASCE Journal of Cold Regions Engineering Award for his work on seismic behavior of bridges in extreme environments.
Dr. Kowalsky is co author of the textbook, Displacement Based Seismic Design of Structures. His students are usually involved in a combination of large-scale structural experimentation and non linear dynamic analysis aimed at developing solutions to problems facing the earthquake engineering community.
