Summary of Work Experience in Management, R&D and Engineering
Current position is Manager of Finite Element Department at RAM International, a leading structural engineering software company head-quartered in Carlsbad, Southern California. Responsibilities at the department include managing finite element application development team, coordinating product support to customers and carrying out product-oriented research and development.
Started a world-class Finite Element Department at RAM International and successfully made it a critical and integral part of the firm and its flagship product, Ram Structural System™.
Designed, coded, QA’ed and maintained an award-winning 3D FE analysis software (RAM Frame™) for building and industrial structures. The program was the winner of 1997 AISC Modern Steel Construction’s Hot Product Competition and is used by about 5000 engineers in 550+ firms in the US and abroad. Program features include linear static, second-order and dynamic analysis of both low-rise and tall buildings and industrial structures. Wind and seismic loads are automatically calculated by the program as per US and International building codes. Floor mass, center of mass and mass moment of inertia and eccentricities for accidental torsion code requirements are also evaluated by the program. Some of the projects where the program was used include: New York Mercantile Exchange in Manhattan, Denver Pavilions, Terminal 2 of the San Diego International Airport, Aladdin Hotel Complex in Las Vegas and numerous industrial structures in the US and abroad.
Currently developing an OOP FE code in C++ for a foundation module and energy-based optimization tool. Graphic interface design is also included in the project. The finite element code will also be available in a client/server mode with COM interface. Also currently responsible for support of a nonlinear analysis program used for rehabilitation and retrofit of major structures such as Hospitals, City Halls, Federal and State Administrative Buildings, etc. as per FEMA-273 and ATC-40 guidelines.
Advanced level experience in structural analysis and design of buildings. Experience includes earthquake engineering and analysis of buildings under seismic and wind loads. Duty includes advising hundreds of engineers and clients in advanced modeling of building and industrial structures for linear static, second-order and dynamic analysis, reviewing lateral load resisting systems and structural member designs of clients and suggesting improvements and reconsideration of frame configurations and selections.
Extensive experience as a consultant on FE theory and software development. Advised on FE modeling and coding for stability and post-buckling analysis of a shell case made of low-modulus soft core. Also consulted in modeling and coding a computational fluid mechanics problem (i.e., shock wave boundary layer interface) using finite difference scheme. Experience also includes non-linear and post-buckling analysis of structural members. Wrote a software for the analysis of such structures using the theory developed. The program is used for the analysis of both stiffened and bare shell structures such as aircraft fuselage, auto body frames, pressure pipes and conduits, reactor housings, etc.
Extensive and advanced level experience in software design, development, testing and maintenance in C, C++ and FORTRAN languages with OOP style in Win 95 and NT platforms for scientific computation applications. Experience includes developing and implementing a rigorous QA procedure for a large project.
Extensive experience in numerical analysis and solution algorithms for large-scale computing in Wintel architecture environment. Devised and implemented practical and efficient storage schemes for large matrices for both 16-bit and 32-bit PC architecture.
Experience in bridge engineering. Experience includes writing an interactive software for analysis of box-girder bridges under static loads. Also extended the application of an analytical method to include practical loading patterns as stipulated in reinforced, steel and pre-stressed bridge codes. The program offers a quick and economical analytical tool during the preliminary design process for box-girder and I-girder bridges.
