Performance of Cantilever Beam in Fire

Introduction:

This paper presents results from an experimental study on the temperature effect of reinforced concrete cantilever beam.

Methods:

Three cantilever beams with fixed end were tested in fire furnace, the distribution of temperature field, the deformation law and the fire resistance of the cantilever beam were obtained.

Results:

Results from these tests indicate that the horizontal section of the temperature curve is about 100 degrees centigrade. The bending capacity of the beam is weaken at high temperature and the failure mode of beam is bending failure. Data from tests also indicates that the plastic hinge of the end of beam moves outward about 240 mm.
