Continuous Real-Time Hybrid Simulation Method for Structures Subject to Fire

X. Wang, R. E. Kim, et al.

Discover a groundbreaking continuous hybrid fire-simulation method that enhances real-time simulations of complex numerical models. This innovative approach, developed by Xuguang Wang, Robin E. Kim, Oh-Sung Kwon, In-Hwan Yeo, and Jae-Kwon Ahn, effectively manages elastic deformation in loading frames for accurate high-temperature structural behavior analysis.

Abstract
This paper presents a robust continuous hybrid fire-simulation method enabling the use of complex numerical models in real-time hybrid fire simulations. Extrapolation and interpolation continuously generate displacement commands, compensating for loading frame elastic deformation. The method's stability, considering loading system stiffness and the error-compensation scheme, is thoroughly discussed. A large-scale hybrid fire simulation on a steel moment-resisting frame validated the method's accuracy in simulating high-temperature structural behavior and failure.
