The use of composite floors is now the one of most preferred methods for a wide range of commercial buildings in the world, offering significant advantages, such as speed, slmp!icity and greater accuracy of construction, flexibility of further floor modification and reduction of construction cost. However, since steel is well known to lose its strength and stiffness properties under elevated temperatures, the fire resistance of the composite construction needs to be investigated. This research is organized to numerically study the structural performance of 4.4m TSC beam under a standard ISO fire, which composite system is developed by SEN Structural Engineering Ltd. Steel and concrete properties under elevated temperatures are obtained from Eurocode and the temperature development across the section IS suggested from mathematlcal methods and heat transfer FE analyses. Based on a modified plastic section capacity, the fire performance of the model is also examined
