Reinforced Concrete Complete Study Review
Concrete in which steel reinforcement is embedded in
reinforced concrete such a manner that the two materials act together in
resisting forces. Also called beton arme,ferro concrete
System of steel bars, strength or wires for absorbing sten-
Reinforcement sile, shearing and sometimes the compressive stresses in
a concrete member or structure
Steel bar for enforcing concrete, usually specified by the
Reinforcing bar number equivalent to its diameter in eight of an inch. Also
called rebar
Reinforcing bar hot rolled with surface deformations to
Deform bar
develop greater bond with concrete
Tension reinforcement Rainforcement designed to absorb tensile stresses
Compression reinforcement Reinforcement designed to absorb compressive stresses
The depth of concrete section measured from compres-
Ettective depth
sion face to the centroid of the tension reinforcement
The center to center spacing of parallel reinforcing bar,
resulting clear distance between the bar being regula ted
Bar spacing
by bar diameter, maximum size of coarse aggregate, and
thickness of the concrete section
The amount of concrete required to protect steel rein-
forcement from fire and corrosion, measured from surface
Cover
to the reinforcement to the outer surface of the concrete
section
The adhesion between two substances such as concrete
Bond
and reinforcing bars
The adhesive force per unit area of contact between the
bond stress rain forcing bar in the surrounding concrete developed at
any section of a flexural a member
Plain concrete
, Concrete having no enforcement or reinforced only for
drying shrinkage or thermal stresses
Constructed of cement and mortar over a wire mesh that
Ferrocement
has been pre shape over a mold
Concrete section design or analyzed on the assumption
Cracked section
that concrete has no resistance to tensile stresses
The load that causes the tensile stresses in a concrete
Cracking load
