Post-Earthquake Fire Resistance of Ductile Concrete Filled Double-Skin Tube Columns
The main idea in this project is to examine concrete filled double-skin tubular columns for multi-hazard situations. Both analytical and experimental studies will be performed on different models to simulate the complete scenario of the earthquake and the following fire. Showing acceptable performance when subjected to fires in past studies along with the fact that these type of composite columns can use the benefits from both steel and concrete parts to behave well under conventional seismic loadings, it is expected that the overall performance of the models when subjected to post earthquake fire scenarios would be much better than typical structural members.
