An Experimental Study on Structural Behaviour of Asymmetric H Beam Slimfloor under Load Condition in Fire

The temperature development of a structural element is dependent on section factor, which is estimated as a ratio of the fire-exposed perimeter to the cross-section area. Hence, with the higher section factor, the faster temperature development of the section os observed. Composite beam member, partially embedded asymmetry H beam, has a good fire resistance to the cross-section. The study was intended to conduct with effect on load ratio, fireproof, reinforcement. The result which the Slim Beam Floor is change to fire resistance performance at 70 minutes for load rate is reduced to the extent of 0.1 and it can have a fire resistance performance for 3 hour when it is design of fire resistance in bottom flange. When it is reinforced with rebar for which can make improve a stiffness on bottom flange in fire, it can control to deflection of component.
