Title

Experimental Modeling Of The Structural Response To Fire Loads Using The Hybrid Simulation Technique

Abstract

The hybrid simulation technique has commonly been used to investigate structural response to earthquake excitation. A hybrid model consists of numerical and physical substructures, which interact at each time step of the solution of the equation of motion for an applied dynamic excitation. The physical substructure's displacements are determined by maintaining deformation compatibility and force equilibrium conditions at the interface between the numerical and physical substructures throughout the simulation. A new hybrid thermo-mechanical simulation capability allows for conducting a hybrid simulation with combined mechanical and fire loads. Implementation was accomplished by extending the existing class structure in OpenFresco. Two proof-of-concept tests were performed to demonstrate the new capabilities using a one-degree-of-freedom hybrid model. The numerical portion of the model was implemented using OpenSees, and the physical portion of the model was exposed to combined axial loads and a standard ISO 834 fire load using a universal testing machine and an electric furnace.
