Eisa Rahmani

Senior Associate


Eisa Rahmani’s expertise is in finite element modeling and analysis of structural systems composed of various civil, structural, and mechanical engineering materials such as reinforced concrete, steel, asphalt concrete, and granular materials.  Dr. Rahmani conducts numerous projects involving structural analysis and evaluation, and condition assessment of various structures using nonlinear finite element analysis, classical methods, and industry design codes. He has been using Abaqus finite element software since 2011 and has experience with ATENA structural analysis software for reinforced concrete. 

Dr. Rahmani’s graduate work focused on numerical modeling and laboratory calibration and validation of damage behavior of asphalt concrete materials under environmental effects. He has published papers in various engineering journals and conference proceedings. Before his graduate work, he focused on the structural design of various commercial and industrial steel structures using commercial design software.
