Abstract

This paper presented an experimental tests for 12 reinforced concrete beams test contained low steel fiber volume in post-burn conditions. Beam experiments were designed in such a way in order to the collapse mechanism of one point load behaved dominant in shear failure. The main parameter that was reviewed in the experiment was spacing of shear reinforcement and temperature (normal, 300oC, 600oC, 900oC). Result of the experiment showed that the collapse mode of specimens at all temperatures was not pure shear. This was signified by the appearance of cracks that occurred around the middle of the span before the beam was crushing. This behavior indicated the role of steel fibers in increasing the shear capacity of beams.
