The Richard J. Carroll Memorial Lectureship

The Richard J. Carroll Memorial Lectureship in Civil Engineering was established at Johns Hopkins University to commemorate one of Baltimore’s leading structural engineers. The lectureship has been endowed by the many friends and admirers of Richard Carroll, who died in 1982. That endowment contributes to the ongoing guest seminars in the Department of Civil and Systems Engineering and provides for these special lectures.

Richard J. Carroll received his bachelor of civil engineering degree from Villanova University in 1955. He studied advanced structural design at Johns Hopkins University and George Washington University. He was chief structural engineer for the firms of Knoerle, Bender, Stone, and Associates, and Ewell, Bomhardt and Associates, and chief field engineer for the Portland Cement Association. In 1964, he founded his own firm, Carroll Engineering, Inc., which grew to 26 employees under his leadership. Mr. Carroll published several papers dealing with concrete use and design, with emphasis on post-tensioned and pre-stressed concrete. He also taught courses in ultimate strength design and plastic design in steel. He belonged to numerous professional societies. His untimely death at the age of 49 left a legacy of professionalism, integrity, and vigor.

Learning from Observation of the Performance of Our Built Environment in the 21st Century”

Prior to the advent of modern structural theory, we built amazing structures—from the Egyptian pyramids to gothic cathedrals—through observation of the performance of our built environment. When performance was good, we were emboldened to build larger and more daring structures. When failure occurred, we adapted and often innovated.

In the past two centuries, our attention to observation of the built environment has, unfortunately, diminished. This is in part due to increasing reliance on mathematical structural theory, but also because today’s legal and cultural environment makes it difficult to share lessons from failures.

Renewed interest and activity promise a renaissance in structural observation that will again allow it to play an impactful role (along with structural analysis and laboratory testing) in advancing the technical and procedural bases for structural engineering. Recent advances include structural health monitoring, performance-based design, and the 2019 launch of Confidential Reporting on Structural Safety in the U.S.

  • Linda Nozik, Director and Professor of Civil and Environmental Engineering, Cornell University

    On March 13, 2019, Linda Nozik, Director and Professor of Civil and Environmental Engineering at Cornell University, presented the 2019 Carroll Lecture. Her talk, titled, “Optimizing the Issuance of Evacuation Orders Under Evolving Hurricane Threat” discussed a bi-level programming model to optimize the issuance of evacuation orders with explicit consideration of (i) the highly uncertain evolution of the storm, and (ii) the complexity of the behavioral reaction to evolving storm conditions. A realistic case study for the eastern portion of the state of North Carolina was presented. Event brochure with more information
