Fire resistance of steel frames under different fire-after-earthquake scenarios based on scaled design accelerograms
The scope of this paper is to examine the performance of a steel framed structure under fire conditions after earthquake events. Taking into account this combined scenario, it is clear that the fire behavior of steel structures depends on the intensity of the ground motion and the study should be based on the performance based design philosophy. For this purpose a three-dimensional beam finite element model is developed using the non-linear analysis code MSC Marc. The combined scenario involves two different stages: during the first stage, the structure is subjected to the ground motion record while in the second stage the fire occurs. Several time-acceleration records are examined, each scaled to multiple levels of the Peak Ground Acceleration (PGA). The objective is to relate, the level of damage of the structural members occurring due to earthquake, to the fire-resistance of the structure.
