Dr. Khalid Alkady specializes in structural health and vibration monitoring of buildings and bridges, dynamic and static laboratory testing of large-scale structures, surveying structural damage using Lidar technology and photogrammetric techniques, and modal analysis and system identification. He employs remote sensing technologies (such as Lidar, cameras, and UAVs), alongside computer vision and machine learning (ML) algorithms, to remotely monitor the dynamic response of structures and components. Additionally, Dr. Alkady specializes in non-linear finite element modeling of structural systems. During his Ph.D. studies, he received the prestigious 2022 UTC Outstanding Student of the Year Award from the U.S. Department of Transportation (DOT) in recognition of his interdisciplinary academic achievements.
Dr. Alkady's doctoral research focused on enhancing civil infrastructure systems through Lidar-based dynamic monitoring frameworks and phased-construction bridges. He developed novel spatio-temporal frameworks that integrate signal processing and ML algorithms to remotely monitor dynamic responses and conduct system identification of structures using dynamic point clouds from Lidar scanners. These frameworks have been successfully applied to monitor the full-field out-of-plane response of a large-scale unreinforced masonry structure during shake-table tests, and conduct system identification of a highway bridge. He conducted extensive controlled-laboratory operational modal analysis tests to assess the robustness of these frameworks under various operational scenarios, utilizing statistical analyses.
His research also examined the impact of traffic-induced vibrations on the structural integrity and durability of bridge decks built in stages. To investigate this, Dr. Alkady conducted ambient-vibration monitoring and system identification of phased-construction bridges before, during, and after construction stages. He further explored this issue with large-scale dynamic and static experimental testing of full-scale phased-construction bridge decks, using servo-hydraulic actuators to simulate traffic-induced vibrations observed in the field.
During his Master's studies, Dr. Alkady performed non-linear response history analyses to assess the seismic behavior of self-centering steel plate shear walls (SC-SPSWs), focusing on the effect of wall aspect ratio. Prior to joining Ä¢¹½tv, he collaborated with researchers at Sandia National Laboratories to study the non-linear dynamic response of bolted joints, utilizing high-speed cameras, stereo-digital image correlation, and piezoelectric ultrasonic transducers during his internship at Sandia.
