To study the anti-fire performance of post-installed rebar anchorage system

the pull-out test is carried out on 35 steel pipe specimens at elevated temperature（25°C～200°C） and the fire test is conducted on 12 bonded rebar connection members.The pull-out test study focuses on the relationship of adhesive strength and temperature and bond-slip relationships of adhesive at high temperatures

which indicates that the bond strength of structural adhesives decreases remarkably with the increase of temperature.In fire endurance test and ultimate strength test

3 coverage thicknesses and 2 embedment depths are considerated.In the ultimate strength test

6 specimens are subjected to the ISO834 fire for a specified time with a constant load

which is set to be 10 percent of the design loading capacity of the same specimens at ambient temperature

and then the load increases till the specimens fail.The test results show that both coverage coat and embedment depth have significant effects on the ultimate strength of post-installed rebar connection members in the fire.In the fire endurance test

6 specimens are subjected to the ISO834 fire till the specimens fail with a constant load

which is set to 80 percent of the design loading capacity of the same specimens at ambient temperature.The test results indicate that both coverage thickness and embedment depth have significant effect on the fire resistance when the coverage thickness is less than 40mm;the embedment depth plays more important role when the coverage thickness is more than 40 mm.
