337103-4 - Application of Nonlinear FE Analysis to Seismic Assessment of Nuclear Power Plant Structures

Friday, April 20
1:30 PM - 3:00 PM
Location: 202CD

How does this session impact and improve the Structural Engineering Profession?
Seismic assessment is essential for engineers in many countries. Knowledge of advanced computational methods creates new leaders. Increased use of advanced simulation has a global and social impact on the profession. Team work is essential because of multi-disciplinary nature of advanced simulation, which is the future in all engineering fields.

Case studies will be presented on practical applications of nonlinear finite element analysis to seismic assessment of reinforced concrete containments and buildings in nuclear power plants. Examples will be presented from recent European stress tests involving pushover analysis of outer containment structure and a critical reinforced concrete building housing the plant control room. The presented examples will be supplemented by results from the analysis of a recent CASH benchmark experimental program on seismic capacity of reinforced concrete shear walls.

Is this topic of regional, national or international interest?
The topic is of international interest in all countries with medium to high seismic risk.

Who is the target audience?
The target audience is design professionals involved in seismic assessment or design of safety critical structures such as nuclear power plants, bridges or high-rise buildings. The topic would be of interest to practitioners involved in the analysis and seismic assessment of structures for all levels of employment.

What will the audience take away from your presentation?
The audience will learn about the computational methods, modeling techniques, suitable finite elements, techniques for modeling reinforcement in large scale problems and about the involved uncertainties based on practical engineering projects of seismic assessment of safety critical structures. The presented case studies were performed in commercial finite element software, so the presented methods and approaches are available in other programs as well, so the engineers can use them in their own work.

The presented techniques and approaches provide practical solutions to problems many engineers are facing when making seismic assessment of critical structures, and they will improve the accuracy, safety and reliability of their design.

He received his Ph.D, at the University of Colorado at Boulder in 1994. He has a strong research as well as practical oriented experience in application of advanced information technology in engineering problems such as: advanced mathematical and numerical modelling of brittle and heterogeneous materials, simulation of engineering structures, grid/cloud/parallel computing of engineering problems, modelling of smart/intelligent structures/buildings. His professional goal is to strive for new development in these methods and bring them closer to practicing engineers and to extend the applicability of these modern methods in engineering practice. He is a member of ACI, FramCoS, fib where he is active in committees on finite element modelling and numerical methods and 3D analysis of creep and shrinkage. He is active in CEN committees on preparation of new Eurocodes. He was involved in the preparation of the fib model code 2010 namely in the chapters for concrete constitutive modelling and safety formats for nonlinear analysis. He is an author of more that 60 papers and conference publications.
