Ayman Elzohairy received his doctorate in civil/structural engineering from the University of Missouri-Columbia. His research focuses on material testing, steel-concrete composite structures, experimental testing and numerical analysis of structural elements, and performance and strengthening of steel-concrete composite bridges. His research has been presented in several articles published in ASCE journals and conference proceedings.

Dr. Elzohairy is a professional engineer with the Texas Board of Professional Engineers and Land Surveyors. His industrial experiences are particularly focused on structural analysis and design of high-rise buildings and bridges. He has a broad range of teaching experience.

Dr. Elzohairy teaches courses in structural analysis and design. He is also interested in teaching civil engineering courses including engineering hydrology and hydraulics, surveying for construction, and AutoCAD.

What would you tell a student who is thinking about attending A&M-Commerce?

“Attending A&M-Commerce is a great opportunity to be part of an integrated system for learning and building your career. A&M-Commerce has programs which are unique in value and experience, including the Construction Engineering program (CONE). This program offers the opportunity to meet with excellent professors and access to quality resources and collaboration opportunities to learn, develop and grow your career.”

What is a current or recent research project or article that you’re proud of?

“I am currently working on a research project to investigate the effects of environmental conditions on the mechanical properties of rubberized high-strength concrete. These conditions include freeze and thaw cycles, temperature and salt attack. Moreover, the effect of adding stainless-steel fibers to the rubberized concrete is investigated to utilize the advantages of both rubber and stainless-steel fibers in concrete. Concrete specimens are prepared with different percentages of rubber and steel fibers, cured and stored under different environmental conditions.”

What has been your favorite course to teach?

“My favorite course is Structure Analysis and Design for the opportunity it provides for students to learn the basics of being a structure engineer. The course offers many topics related to structure and bridge engineers. During the course, we also work on using RISA 2-D software to analyze structures. This has been guiding students to improve their skills and build their careers as structure engineers.”
