M.Sc. (The University of Calgary) 1982

Dr. El-Badry has extensive industrial, consulting and academic teaching and research experience in the area of Structural Engineering since 1976. Before joining the Department in January 2000, he held faculty and administrative positions at Concordia University in Montréal from 1992 to 1999. He was Adjunct Professor at the University of Calgary from 1990 to 1999 and Visiting Professor in 1998-1999. He is a Project Leader in the Network of Centres of Excellence, ISIS Canada, on "Intelligent Sensing for Innovative Structures". He is also member of the research team on monitoring the performance of the Confederation Bridge. He is co-author of the third edition of the book on Concrete Structures: Stresses and Deformations, by Ghali, A., Favre, R., and Elbadry, M., Spon Press, 2002, 608 pp. He is also author of several computer programs for the analysis, design and evaluation of bridges and other structures.
Dr. El-Badry's research interests are in the following topics:
Work undertaken in these areas involves numerical modelling and experimental and analytical studies, all aiming at establishing better understanding of the behaviour of concrete structures and developing computer-based analysis and design procedures and tools suitable for use in practice. Several computer programs have been developed based on this research and are now in use by numerous organizations worldwide for analysis, design and performance evaluation of major bridges and other structures.
Current research projects include:
1. Use of Fibre Reinforced Polymers (FRP) in concrete structures: several investigations under this topic are currently in progress including: development of innovative corrosion-free bridge systems; temperature effects on concrete structures reinforced with FRP; optimum design of precast bridge systems prestressed with FRP tendons; serviceability and strength of concrete slabs reinforced with FRP; strengthening of concrete structures with externally prestressed FRP tendons; retrofitting of prestressed concrete railway crossties with fibre composite fabrics; seismic rehabilitation of concrete beam-column joints with FRP laminates.
2. Serviceability and strength of concrete structures: numerical procedures and computer programs have been developed for the analysis of time-dependent stresses and deformations of a wide range of concrete structures due to the effects of creep and shrinkage of concrete, relaxation of prestressing steel, cracking and tension stiffening of concrete, and temperature variations. Structures that can be analyzed include: continuous bridges built span-by-span; segmental construction or structures built up of precast prestressed concrete members connected and made continuous by cast-in-situ concrete deck or joints and a second stage prestressing; multi-storey structures (Programs RPM, CRACK, and CPF: Cracked Plane Frames in Prestressed Concrete); and segmentally erected curved prestressed concrete box-girder bridges (Program TD-SFRAME: Time-Dependent Analysis of Space FRAMEs).
3. Monitoring performance of the Confederation Bridge: field measurements and laboratory testing of properties of concrete and prestressing steel used in construction of the bridge are on-going. Code equations for prediction of the time-dependent material properties are calibrated by the measured values and new equations are developed. Also, short- and long-term deflections have been measured during construction, and in truck-loading tests and at several time intervals after completion of the bridge. The measured deflections are compared with the results of computer analyses using Program CPF and good agreement is obtained, particularly when the measured material properties and the effects of temperature variations are included in the analysis.
4. Temperature effects on concrete structures: numerical procedures and computer programs based on finite element techniques for heat transfer and stress analysis have been developed to determine temperature variations due to weather conditions, and the induced thermal stresses in bridge structures and storage tanks. Two programs, FETAB and FETAB-3D are now available for two- and three-dimensional Finite Element Thermal Analysis of Bridges. Also, design guidelines have been established for control of thermal cracking in reinforced concrete structures with or without prestressing.
5. Seismic behaviour of cable-stayed bridges: numerical studies have been conducted on the effects of cable vibration, support conditions, tower stiffness and soil conditions on the earthquake response of conventional and multi-span cable-stayed bridges.
Since 1988, Dr. El-Badry has taught the following undergraduate and graduate courses at both the University of Calgary and Concordia University:
Dr. El-Badry has served as consultant on the analysis and design of major heavy industrial projects and building and bridge structures in Canada, U.S.A., Korea, France and Saudi Arabia.
Dr. El-Badry was the Chair of the Fourth International Conference on Advanced Composite Materials in Bridges and Structures, ACMBS-IV, held in Calgary in July 20-23, 2004. He also participated or is participating in organizing several national and international conferences as:
