Gracing the Sky, Enriching the City

Friday, February 28, 2020– 4:30 pm

Location: Whitaker Lab 303, Lehigh University, 5 East Packer Avenue, Bethlehem, PA

Overview:

“The city is more important than the building and the building is more important than the architect.”  - Cesar Pelli

Tall buildings have the ability to define corporations, cities and even nations. As iconic as some towers may be perceived, their true success is in how they positively contribute to their cityscape and, perhaps most importantly, how they improve and enrich the lives of those who live and work every day in the community. As noted by Fazlur Rahman Khan, “Life is art, drama, music, and most importantly, people.” Using examples of tall buildings he has designed worldwide, Jon Pickard will speak to the responsibility architects of skyscrapers have in reimagining ground level experiences to serve as a benefit to both the public and the environment.

PHILLIP L. GOULD

Senior Professor
Washington University

From Slide Rule to FEA: Some Stops Along the Way

Friday, March 20, 2020– 4:30 pm

Location: Whitaker Lab 303, Lehigh University, 5 East Packer Avenue, Bethlehem, PA

Overview:

Brief comments on the authorís professional career, from an aspiring structural designer of buildings and bridges to further graduate study and then an academic and research career, are offered. Dr. Gouldís 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.

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 Khanís early career. These include his applications of classical structural engineering methods in the pre-computer era and his outstanding interpersonal relationships with architects, engineers and members of the building community.
 
Moving on to applications of the research of Dr. Gould and his students, potentially destructive loading conditions that have impacted chimneys and cooling towers are briefly described. While chimneys and cooling towers of increasing height have been successfully constructed for decades, in the present context of resiliency they both possess an undesirable structural characteristic in that they are globally statically determinate. Dr. Gouldís studies of extreme events that caused a severely damaged cooling tower and a collapsed chimney are used to illustrate selected aspects of their structural performance. The response of each structure is examined with the objective of validating and augmenting design characteristics that may improve their behavior under any imaginable loading condition. The application of nonlinear analysis techniques that may be useful in predicting the response of such structures to multihazard design conditions beyond current code requirements is suggested.

From Performance-Based Earthquake Engineering to Functional Recovery and Resilience

Friday, April 17, 2020– 4:30 pm

Location: Whitaker Lab 303, Lehigh University, 5 East Packer Avenue, Bethlehem, PA

Overview:

Performance-based earthquake engineering has matured over the past twenty years from a conceptual framework into a formal methodology that can enable quantitative assessment of the seismic risks to buildings and infrastructure.  Enabled by advanced computational technologies, performance-based methods provide for more transparent design and decision making that takes advantage of the latest research in characterizing earthquake ground motion hazards, simulating structural behavior, and assessing earthquake damage and its consequences. Performance-based approaches are facilitating the design of innovative structures and influencing building code requirements and public policies for earthquake safety. Continued developments to extend performance-based engineering to city-scale simulations provide emerging opportunities to engage urban planners, public officials, and other stakeholders in developing strategies to avoid and mitigate risks and improve resilience to earthquakes and other natural hazards.  Examples include new technologies to enable high-resolution earthquake scenario studies and earthquake policy initiatives in San Francisco and Los Angeles.
