Structural Performance of Slim Beam Floor System in Fire

摘要

This paper presents a numerical study to predict the in-fire performance of slim floor system, composed of asymmetric steel beam, deep steel decking and in-situ concrete slab. The reliability of the proposed numerical model was verified by comparison with experimental results obtained for 4.2m beam tests. A pilot study was also conducted to examine the effect of the cross sectional modification of the steel section on performance enhancement of the model in fire.
