AB  - Precast/prestressed Hollow-Core Slabs (HCS<sub>S</sub>)
are often utilized in construction applications because of
the many benefits they offer compared with traditional
techniques of slab construction. In this study, an
experimental investigation about fire damage on
precast/prestressed (HCS<sub>S</sub>) was performed. Five full-scale
slabs made from Normal Strength Concrete (NSC) were
presented in this study, one of them as a reference slab
(control slab) which is not exposed to fire and the other
four were exposed to fire according to the standard fire
curve (ASTM-E119) with differing exposure durations
and variable cooling methods. After burning processes,
these slabs tested as simply supported under two line-load
at equal distances between these loads and supports, to the
stage of failure. The test results appeared that the initial
stiffness, the ultimate load carrying capacity and the
ultimate vertical deflection for all slabs decreases with
increasing the duration of fire exposure. In addition, the
slab that cooled suddenly by water after burning appeared
slight decrease in these values compared with the slab that
left to cooled, gradually in the air.
