Experimental Study on Fire Resistance Properties of Post-Installed Rebar Connection

Article Preview

Abstract:

A serial of fire tests have been conducted to study the fire resistance of the post-installed rebar connection with organic adhesive. Research variables include three kinds of anchorage depth. Loads are applied to specimens through lever and remain a constant throughout the whole process of the tests. The temperatures of connections are elevated following the ISO834 curve and the failure is controlled by excessive deflection of bonded-in rebar beams. The test results show that anchorage depth has a great influence on the performance of bonded-in rebar beams exposed to fire. Beams using organic adhesive fail suddenly with obvious rebar slip, and behave with poor fire endurance.
