Abstract

The concept of hybrid (experimental-numerical) simulation method was first proposed in 1969 by Hakuno et al. Since then, the hybrid simulation method has been continuously evolved. One of the main strengths of the hybrid simulation is that critical element(s) in a structural system can be tested in a laboratory while the rest of the system can be numerically simulated. In addition, the method can be also used to analyze a large and complex system such as soil-structure interaction problem by substructuring the system to smaller problems that can be solved with dedicated analysis tools for each problem domain. To facilitate the development and application of hybrid (experimental-numerical) or multi-platform (numerical-numerical) simulation method, the University of Toronto has developed a generalized simulation framework, UT-SIM (www.ut-sim.ca). The framework allows integration of various experimental specimens with various numerical analysis tools. The presentation will first introduce the simulation framework for component-level substructuring and system-level substructuring which is followed by applications of the framework to various structural systems subjected to earthquake load such as self-centering energy-dissipative brace system, buckling restrained braced (BRB) frame, special concentric braced frame, and eccentrically braced frame. Applications of the hybrid simulation methods on a structure subjected to fire and wind loads will be briefly discussed.
