  • Major Software Development
    1. MACS© (2001): is an inelastic analysis program that conducts time-dependent analysis of reinforced concrete sections strengthened with carbon fiber reinforced polymer laminates. The program is implemented within a Visual Basic environment and features an easy to use graphical user interface.
    2. DYNAMIX (1996): An inelastic dynamic analysis program for two- and three-dimensional steel, and mixed steel-concrete systems. Implemented in a fully graphically interactive environment for SunOS 5.5, VMS and OpenVMS-AXP systems. School of Civil and Environmental Engineering, Cornell University and Steel Structure Development Center, Nippon Steel Corporation, Chiba, Japan. Principal developer.
    3. COSBIAN (1995): An inelastic analysis program for steel, composite, and reinforced concrete sections subjected to biaxial bending. Implemented in a fully graphically interactive environment for SunOS 5.5, VMS, OpenVMS-AXP systems. School of Civil and Environmental Engineering, Cornell University. Co-developer.
    4. PREPF (1994): A user-friendly, fully graphically interactive preprocessor for framed systems. Computer Aided Design Instructional Facility, Cornell University. Co-developer.
    5. QUAND (1994): An inelastic dynamic analysis program based on the plastic hinge concept for two- and three-dimensional steel systems. School of Civil and Env. Eng., Cornell University. Co-developer.
    6. NARCS1 (1989): An inelastic monotonic analysis program for two-dimensional reinforced concrete plane stress structures. AutoCAD postprocessing. DOS-PC. Faculty of Engineering, Cairo University. Principal developer.
