REINFORCED CONCRETE
QUESTIONS & SOLUTIONS 2026
LATEST UPDATE!!!
reinforced concrete - ANSWERConcrete in which steel reinforcement is embedded in
such a manner that the two materials act together in resisting forces. Also called beton
arme,ferro concrete
Reinforcement - ANSWERSystem of steel bars, strength or wires for absorbing stensile,
shearing and sometimes the compressive stresses in a concrete member or structure
Reinforcing bar - ANSWERSteel bar for enforcing concrete, usually specified by the
number equivalent to its diameter in eight of an inch. Also called rebar
Deform bar - ANSWERReinforcing bar hot rolled with surface deformations to develop
greater bond with concrete
Tension reinforcement - ANSWERRainforcement designed to absorb tensile stresses
Compression reinforcement - ANSWERReinforcement designed to absorb compressive
stresses
Effective depth - ANSWERThe depth of concrete section measured from compression
face to the centroid of the tension reinforcement
Bar spacing - ANSWERThe center to center spacing of parallel reinforcing bar, resulting
clear distance between the bar being regula ted by bar diameter, maximum size of
coarse aggregate, and thickness of the concrete section
Cover - ANSWERThe amount of concrete required to protect steel reinforcement from
fire and corrosion, measured from surface to the reinforcement to the outer surface of
the concrete section
Bond - ANSWERThe adhesion between two substances such as concrete and
reinforcing bars
bond stress - ANSWERThe adhesive force per unit area of contact between the rain
forcing bar in the surrounding concrete developed at any section of a flexural a member
Plain concrete - ANSWERConcrete having no enforcement or reinforced only for drying
shrinkage or thermal stresses
, Ferrocement - ANSWERConstructed of cement and mortar over a wire mesh that has
been pre shape over a mold
Cracked section - ANSWERConcrete section design or analyzed on the assumption
that concrete has no resistance to tensile stresses
Cracking load - ANSWERThe load that causes the tensile stresses in a concrete
member to exceed the tensile strength of the concrete
Effective area of concrete - ANSWERThe area of a concrete section between the
compression face in the centroid of the tension reinforcement
Effective area of reinforcement - ANSWERThe product of the right cross sectional area
of reinforcement in the cosine of the angle between the direction in the direction for
which its effectiveness is considered
percentage reinforcement - ANSWERThe ratio of effective area of reinforcement
effective area of concrete at any section of a reinforced concrete member, expressed as
a percentage
Embedment length - ANSWERthe length of embedded reinforcement provided beyond
a critical section for Anchorage
hook - ANSWERA bend or curve given to the end of a tension bar to develop an
equivalent embedment length, used where there is insufficient room to develop an
adequate embedment length
Standard hook - ANSWER90 degrees, 135 degrees, or 180° been made at the end of a
reinforcing bar according to industry standards with a radius based on the bar diameter
fiber reinforced concrete - ANSWERConcrete reinforced with this purse, randomly
oriented fiber of glass or plastic
GFRC - ANSWERAbbreviation for glass fiber reinforced concrete
Welded wire fabric - ANSWERa grid of longitudinal and transverse steel wires or bars
welded together at all points of intersection, usually specified by the size of the grid in
inches in the wire gauge. Also called welded wire mesh
woven wire fabric - ANSWERA mesh of cold rolled steel wire mechanically twisted
together to form hexagonally shaped openings
Balance section - ANSWERa concrete section in which this the tension reinforcement
theoretically reaches its specified yield strength of the concrete in compression pictures
it's assumed ultimate stream
