Abstract:
This series of seminars starts with the basics of hybrid simulation, which includes the
theory behind the method as well as an overview of the previous research related to
various aspects of the method, namely substructuring, integration methods, simulation
errors, geographically distributed hybrid simulation, and real time hybrid simulation.
The underlying computational platform (OpenSees) and middleware (OpenFresco) used
in hybrid simulation at the University of California, Berkeley and other places will be
briefly introduced. Subsequently, the presentations cover four recent developments
aimed towards faster computations, more accurate execution of real-time hybrid
simulations (RTHS), and recent efforts towards developing a mechanics-based
theoretical foundation of the method. The seminars will cover detailed presentation of
several applications of the hybrid simulation technique applied to (1) columns made of
reinforced auger pressure grout (APG) to be compared to reinforced concrete (RC)
columns, (2) electric substation high voltage disconnect switches, and (3) composite
energy-efficient wood-based structural insulated panels (SIPs). The seminars will
conclude with future plans for extending the method for use in the context of
performance-based earthquake engineering applied to electrical substations, application
to a bridge column-superstructure subassembly subjected to multi-directional ground
motion, and analyzing combined structural/non-structural large-scale systems on
different computational platforms.
About the Speaker:
Prof. Mosalam obtained his BS and MS from Cairo University. In 1996, he earned his
PhD from Cornell University in Structural Engineering. In 1997, he joined the faculty of
the Department of Civil and Environmental Engineering, UCB where he is currently a
professor of structural engineering. He conducts research on the performance and health
monitoring of structural systems of concrete, masonry, and wood subjected to extreme
loads. He is active in the areas of assessment and rehabilitation of essential facilities
such as bridges and electrical substations. His research approach covers large-scale
computations (deterministic and probabilistic) and physical testing including hybrid
simulations. Prof. Mosalam is the recipient of the 2006 ASCE Walter L. Huber Civil
Engineering Research Prize with citation: “For advanced computational research
integrated with large experiments to solve practical structural engineering problems.”
Because of his international collaboration for seismic safety and regulations of low cost
housing in Morocco, Mosalam was awarded the 2013 UCB Chancellor award for Public
Services. Mosalam is active in the area of building energy efficiency and sustainability.
