Résumé
This paper provides results of a hybrid structural test that simulates residual lateral load resistance of a structure after fire damage. The simulation was carried out at the National Research Council of Canada (NRC) using the NRC’s furnace facilities. The hybrid test included two substructures; a structural element/assembly specimen, here a column specimen, and a model component, here the remaining of the structure. Using this method, first, fire damage was imposed to a structure, a 6-storey reinforced concrete building, and six days later, after the entire structure had cooled down to the ambient temperature, the building was subjected to a lateral load, which was determined based on a design seismic load. The test results showed a reduction of both residual lateral stiffness and residual lateral load capacity of the structure after the fire damage. This paper will present the hybrid test, its application and the results for the 6-storey building.
