Abstract
It has long been known that fire could dramatically reduce the characteristic strength of the
reinforced concrete elements. A significant effort has been devoted to study the effect of
fire on the reinforced concrete elements during past decades. Most of the previous studies
were focused on evaluating for concrete elements and its fire resistance, and provided
some recommendations of structural fire- resistance such as cover thickness,
reinforcement ratio and coating materials. A lot of thesis focused on columns, beams and
slabs exposed to fire, where less efforts aimed to study the effect of fire on beam column
connections Consequently, the main objective of the present work is to study the behavior
of reinforced concrete beam-column connections exposed to fire under loading and to
evaluate the reduction in concrete strength during fire. To achieve these goals, this research
is divided into two parts, the first part is experimental program, and the second is the
theoretical analysis. The experimental program include 18 one- third scale specimens half
of them casted from normal concrete and other half of SCC. For each concrete type, 3
specimens were exposed to 600 °C for one hour, other 3 specimens exposed to 600°C for
two hours and last 3 specimens as a control not exposed to fire. The effect of some
parameters on the connection’s behavior like reinforcement ratio, type of concrete (normal
or SCC) , amount of stirrups on connection and exposure time were studied. Experimental
program extended also to study heat distribution inside beam – column connections by
measuring temperature at 65 point Distributors at 5 sections allover connection. Excellent
behavior in fresh and hardened states of both normal concrete and SCC was observed for
reinforced beam- column connections. SCC has good properties in hardening state when
exposed to high temperature compared with normal concrete. Increasing reinforcement
ratio and number of stirrups in connections increases its fire resistance Good agreement
between analytical and experimental work was observed.
