Akbar Pirmoz, PhD, PE

Dr. Pirmoz has nearly two decades of experience in structural engineering and related academic research. He is the president and founder of the company. Before launching Pirmoz Structural Engineering in 2021, he was a project manager at a structural engineering firm in Washington D.C. and was involved with several challenging projects across Mid-Atlantic region and other parts of the world. His engineering experience ranges from microstructure analysis of materials to earthquake-resistant design of tall buildings which covers structural design, performance evaluation, seismic retrofit, construction administration and forensic engineering of a wide spectrum of projects including tall buildings, hospitals, residential and historic buildings, industrial facilities, retaining walls and deep foundations. Many of these projects have been designed against extreme loads such as earthquakes, progressive collapse and flood, demanding advanced structural analyses. One of his featured projects is the structural design of a 36-story hospital with nearly 1.9 million sq.ft. of floor area with steel plate shear walls, special moment resisting frames and rotational friction dampers. His research in structural and earthquake engineering, including material science, steel connections & members, progressive collapse, damped vibration, seismic reliability as well as displacement-based seismic design has been published in several academic journals and conference proceedings. Envisioning the future of high performance materials, he completed his Ph.D. dissertation on the computational simulation of mechanical and electromechanical response of Carbon Nanotube Fibers. He has programmed several finite-element structural analyses codes to overcome the computational limitations of common commercial engineering software in some of his works. He has lectured on Applied Computational Methods in Civil Engineering, a graduate course, at the Catholic University of America (CUA) and on Construction of Metal Buildings at Kamal University. He is also a member of the intelligent material research team at CUA. He is a licensed professional engineer in Virginia, Maryland and Washington, D.C.

The structural design was through Perfromance Based Design concept and using nonlinear pushover analysis of the strucutre. A nonlinear finite element model was created for the analysis of the composite shear walls of the building. The modeling approach was verified using the published laboratory test results of this type of shear wall.
