Overview:

Brief comments on the author’s professional career, from an aspiring structural designer of buildings and bridges to further graduate study and then an academic and research career, are offered. In deference to the namesake of this lecture, based on recollections of a junior engineer working closely with Fazlur Khan, Dr. Gould offers some observations on Khan’s early career. Dr. Gould’s subsequent academic and professional activities initially focused on thin -shell analysis, especially the emerging field of hyperbolic cooling towers. The advanced capabilities of the SHORE family of computer programs that were developed in the course of the shell research provided an important tool in the design and explanation of some unique extreme loading situations for both cooling towers and chimneys. As his career progressed, he became very involved in earthquake engineering with strong focus on education and mid-America issues. In the course of teaching graduate subjects, he authored several textbooks and enabled the dissemination of current knowledge as editor of the journal ENGINEERING STRUCTURES.

A Research Perspective on Seismic Performance of Steel Building Structures

Overview:

Steel buildings designed and constructed in the US and other regions with modern seismic standards are anticipated to perform very well with respect to life safety under the expected earthquake demands. For ground motions at the maximum considered earthquake intensity, the probability of collapse is relatively small; however, the probability of structural and nonstructural damage is relatively large for ground motions with shorter return periods comparable to the expected life of these buildings, so questions about seismic resilience remain. Research to improve steel building seismic performance is ongoing with a focus on reducing damage by reducing global lateral drift, avoiding localization of drift, and reducing accelerations. Recent research results include innovative structural mechanisms, such as self-centering, to permit lateral drift without structural damage, as well as various damping systems to reduce drift. Current research seeks to control distributions of internal forces to minimize drift localization and to reduce accelerations. This presentation provides a perspective on current research questions and research outcomes toward improving steel building seismic performance.
