I learned he was the author of Engineering Iron and Stone: Understanding Structural Analysis and Design Methods of the Late 19th Century. I’ve appreciated that book for several years but in my conversation with Professor Boothby, he suggested that his more recent book Empirical Design in Structural Engineering desired more recognition. He was kind enough to share a copy of his most recent book. I’ve completed reading the book and I must admit that it offers compelling arguments to support utilization of empirical design for structures. The book presents what should be obvious to all of us, that the analytical design process is a very recent development as compared to to the empirical design process which was the only process for a couple of millennia. The book was fascinating as it delved into the relationship, and logic, that many of the existing building codes are based on empirical theory and only marginally supported by analytical research. I was particularly interested in chapter 7, Case Study 1: Empirical design in historic structure assessment and preservation. To get a complete understanding of the author’s message, it was important that I read the preceding chapters. Among other take away, I appreciated learning the transition from purely empirical design to analytical rational design as we are working on several projects designed during that period in history. I agree with the author that empirical design is essential at the onset of projects as a basis from which to develop a successful design solution. I also agree with the author’s concern regarding the means by which to educate engineering students as to education gained by experience. This is not a light reading, but in my opinion is well worth the investment of time if you are an engineer or working with historic structures as an architect or engineer. https://images.squarespace-cdn.com/content/v1/6777100f80265554e10375cf/83c2331c-116b-4fb0-8193-a14dcc9ca150/Boothby%2C+Thomas+2.jpg Blog - Empirical Design in Structural Engineering - About the AUthor Thomas Boothby is a professor of Architectural Engineering at the Pennsylvania State University. He is a registered architect and professional engineer with 40 years of experience in structural engineering as a designer and educator.

He founded his company, Historic HomeWorks in 1971. Throughout his career, he has been a hands-on craftsman learning from mentors and friends in the beginning. As his reputation spread throughout New England, he began offering long-distance consulting which led to the creation of Reports for his clients. For decades he has led workshops on wood restoration. He constantly monitors new wood restoration products, testing each for himself before recommending, or discouraging their use by homeowners and other craftsmen. John has been a reliable, and trusted resource. I have found his Compendium to be an essential reference for wood restoration. https://www.pattithepreservationist.com/blog/water-in-buildings monthly 0.5 2025-12-05 https://images.squarespace-cdn.com/content/v1/6777100f80265554e10375cf/57a5db9d-0f2d-4658-b9c1-892f115265f9/IMG_3227.JPG Blog - Water in Buildings: An Architect’s Guide to Moisture and Mold - Make it stand out Whatever it is, the way you tell your story online can make all the difference. https://images.squarespace-cdn.com/content/v1/6777100f80265554e10375cf/1764888031740-LRVF4BYTF2YHJFKRXAJ6/IMG_3230.JPG Blog - Water in Buildings: An Architect’s Guide to Moisture and Mold https://images.squarespace-cdn.com/content/v1/6777100f80265554e10375cf/1764888027796-U2C0RG1JFWYT988I5DP0/IMG_3236.JPG Blog - Water in Buildings: An Architect’s Guide to Moisture and Mold https://images.squarespace-cdn.com/content/v1/6777100f80265554e10375cf/1764888149478-3Y6VMZ1ARQV81P3EREVO/IMG_3229.JPG Blog - Water in Buildings: An Architect’s Guide to Moisture and Mold https://www.pattithepreservationist.com/blog/recording-historic-structures monthly 0.5 2025-11-25 https://images.squarespace-cdn.com/content/v1/6777100f80265554e10375cf/4fede60a-ae93-4369-966f-63d10b66ce0e/IMG_3177.JPG Blog - Recording Historic Structures - Make it stand out Author: The Staff of HABS/HAER National Park Service, US Department of the Interior, Edited by John Burns.
