336639 - Performance-Based Engineering: State-of-the-art, state-of-practice, and future trends

Friday, April 20
11:00 AM - 12:30 PM
Location: 203BC

Performance-Based Engineering (PBE) is an established philosophy for design, construction, retrofit, and maintenance of engineered systems. During the last two decades, PBE has found significant recognition in the development of modern design codes, particularly for structures subject to seismic hazard. PBE moves away from the prescriptive approach that is common to current design codes and focuses on the engineering system performance from the viewpoints of owners, contractors, designers, and society at large. In structural engineering, this modern concept and the analysis/design methodologies derived from it allow for cost-effective design, construction, and maintenance of facilities. PBE approaches rigorously account for the uncertainties in material properties, geometry, construction methodologies, modeling assumptions, and loading environment.
The panelists will provide the audience an overview of the ongoing efforts in research, codes/standards development, and general promotion of PBE principles within the Structural Engineering community and profession. This multidisciplinary panel will discuss recent advances in the state-of-the-art and state-of-practice of PBE methodologies and applications within the general field of Structural Engineering. The presented advances will cover performance assessment, performance-based design, design optimization, and resilience-based assessment of different types of structures subject to single or multiple hazards, as well as other issues related, e.g., to construction, identification, and aesthetics. The panel format will also be conducive to a constructive debate among panelists and between panelists and audience. This interaction will be encouraged through a substantial Q/A component. The panelists will also present the audience with some open questions, which will have the potential to further the interest and engagement of the audience even after the conclusion of the panel session.
The topic of PBE is of international interest and the target audience include researchers, design professionals, and code developers, from senior to entry levels. The expertise of panelists will cover multiple disciplines, including earthquake, wind, hurricane, and fire engineering, fracture and fatigue of structures, life-cycle analysis, structural safety, and structural identification.
The audience will be introduced to current PBE practice and applications in multiple sub-disciplines of Structural Engineering, including the emerging field of structural fire engineering. The audience will also be informed of current ongoing and future planned efforts to introduce modern PBE principles into existing design codes, as well as develop new performance-based design codes and standards. The interaction among the panelists, who represent numerous different SEI technical committees as well as an SEI Board-level Task Committee of Governors, will provide the groundwork for potential future collaborations among the multiple co-sponsoring SEI committees. Finally, it is expected that this panel session will help define the SEI vision for the impact that PBE will have on the future of Structural Engineering.
