Thomas Cain, M.S., EIT

Thomas Cain graduated from the University of Oklahoma in May 2020 and joined PEC shortly thereafter. He supports design projects for blast resistant structures and building components in new construction, as well as assessment of existing facilities for potential retrofit or renovation to resist explosive threats. He is experienced in the use of MATLAB and Mathematica for modeling purposes, and in the application of Revit, RAM Elements, and SBEDS, among other tools, for structural design. Thomas has written a technical paper on “Modeling, Characterizing, and Testing a Simple, Smooth Negative-Stiffness Device to Achieve Apparent Weakening” that has been published and can be read here.

Thomas earned his Bachelor of Science in Architectural Engineering from the University of Oklahoma in 2019 and completed his Master of Science in Civil Engineering with a structural emphasis in 2020. His Master’s research focused on developing devices for seismic mitigation that utilized nonlinear dynamic effects.

Stephen Bratz

Stephen joined Protection Engineering Consultants (PEC) in April of 2019. He holds a Master of Science degree in Structural Engineering from the University of Texas at San Antonio, where he researched the effects of welding on high mast illumination poles using the Abaqus Welding Interface (AWI) in his thesis. He also earned a Bachelor of Science degree in Physics from Texas Lutheran University.

Stephen provides support for design projects for blast and impact resistance of structures and glazing systems. In addition, he supports research efforts focused on the response of structures and construction materials subjected to blast loading and other extreme events. He has experience with MATLAB and various finite element software tools such as Abaqus and SAP2000.

Stephen will be supporting PEC and our clients on both research and design efforts, and can be contacted at 512-380-1988 x325 or
