Dr. Ibrahim M. Metwally, is a professor of concrete structures at the Concrete Structures Research Institute at the Housing and Building National Research Center, Cairo, Egypt. He holds B. Sc., M. Sc., and Ph.D. degrees in structural engineering. Experienced in both the academia and industry fields. His research interests include ultra-high-performance concrete, the performance of structures exposed to extreme loading, large-scale experimental testing, the behavior of concrete structures reinforced with FRP composites & analysis, and the design of tall buildings. He has been heavily involved in structural design, performance-based seismic design/assessment, retrofitting, and testing. Dr. Metwally is also a committee member of the well-known international design code ACI 369.1-17 ( Seismic Evaluation and Retrofit of Existing Concrete Buildings). Dr. Metwally is also member of the committee preparing the Egyptian Code for the Design and Construction of Reinforced Concrete Structures, member of the committee preparing the Egyptian Code of Practice for the Use of Fiber Reinforced Polymer (FRP) in the Construction Fields, & member of the committee preparing the Egyptian Code for Retrofitting Design of Concrete Structures. He is registered as a structural consulting engineer at the Ministry of Housing, Utilities & Urban Communities, Egypt; he has designed, and evaluated many structural designs for huge projects in Egypt and Arabian Gulf region. Dr. Metwally is licensed as a Professional Engineer(PE) by the Wyoming Board of Professional Engineers in the USA. His extensive hands-on experience includes the structural design and analysis of multi-story buildings using structural steel, reinforced concrete, post-tensioned and pre-stressed concrete, deep foundations, and structural masonry. He provided structural forensic studies and structural damage assessments throughout many locations around the world. Dr. Metwally served as a credible expert witness and he analyzed and evaluated the cause of failures in a wide variety of structures, such as bridges, buildings, industrial structures, and metro stations under different extreme loading conditions.
