In
most cases, reinforced concrete uses steel rebels that have been
inserted to add strength. Concrete is reinforced to give it extra
tensile strength; without reinforcement, many concrete building would
not have been possible.
Reinforced concrete can compasses many members or types of structures and components which includes:
Slabs
Walls
Beams
Columns
Foundations
Frames and more
Reinforced concrete can be classified as (1) pre-cast and (2) in-situ concrete.
Reinforced
concrete is focused mainly on the floor system. Designing and
implementing the most efficient floor system is key to creating optimal
building structures, small changes in the design of a floor can have a
significant impact on material cost; construction schedule, ultimate
strength, operating costs, occupancy levels and end use of building.
REINFORCEMENT AND TERMINOLOGY OF MEMBERS
It
is found that the architectural drawing has been thoroughly examined
and right systems of design have been chosen. In this modern computer
age, the easiest way to carry out design is by computer method, but the
system of manual method is still use to arrive at the same point going
through all the worst critical members of the structure by using the
factors like
Ly/Lx ≤ 2.0 for two-way slab
Ly/Lx ≥ 2.0 for one-way spacing
The
load on this slab is being estimated using the appropriate moments
data, shears, torsion, the reinforcement are calculated using the
appropriate method of provided by design code.
The moment
coefficients given in the code and moment distribution method were
employed in the determination of slabs and beam moments while the
analyses of the substitute frame were used for columns.
Beams bending
in small curvature at the outer face (tensile face) of the curvature
the concrete experiences tensile stresses while at the inner face,
(compressive face) it experiences the compressive stress.
The slab and beam and also the roof structure causes axial load on the column.
Reinforcement are been provided to each of the members after deign using the appropriate chart from design codes.
The column transfers loads from slab and beam down to the foundation and distribute same to the soil.
The
shear reinforcement where also calculated providing the reinforcement
with the appropriate table approved by design code in respects of the
value gotten. The shear reinforcement is in form of links, stirrup where
also provided where necessary.
