Abstract

In this paper, the effect of previous heating on load-slip relationship in modified
push-out test is studied. Specimens of concrete slab with connectors (connector embedded
in the concrete slab) were put in an oven of high heating for at least one hour after
reaching a specified temperature (300~700) oC. Due to these high temperatures, the
compressive strength of concrete was reduced and cracks were seen on the surface of
concrete. The slip was increased and the stiffness of the connector was decreased
significantly. It is concluded that the effect of previous heating on the connector stiffness is
greater than its effect on the compressive strength of concrete due to presence of cracks in
concrete after heating to high temperatures.
