Abstract:
Tension in section of
reinforced concrete of beam divided to depress area and interesting
area. In the plan depress area to be accepted by interesting area and
concrete is fully accepted by bone, and interesting strength of concrete
disregarded.
In efficiency to materials, hence logically interesting
area can be made by quality of lower concrete compared to with quality
of area concrete depress. So that the reinforced concrete of beam
structure can be made is composite of concrete, by differentiating
quality of concrete at interesting area and depress area. This
opportunity will be studied by composite influence of the concrete at
flexure behavior. Research done by making speciment of concrete beam
with manipulation comparison of saction of depress area, using quality
of higher concrete and interesting area which use quality of lower
concrete. To perceive flexurer behavior, is also compared to concrete
beam having saction entirely high quality and entirely have low quality.
Besides perceiving flexure behavior also wish to be studied by
interesting strength contribution of concrete at interesting area, is
which during the time disregarded. The result of research indicate
that ever greaterly of area quality of high concrete, ever greater
flexure strength, and ever greater also strength arrest, so that in
comparison with beam having saction of low quality all, deflection of
saction higher composite, is but compared to with concrete beam having
saction of high quality, deflection of saction composite of lower. This
condition indicate that interesting strength of concrete also give
contribution at interesting strength of beam, posed at with make-up of
big enough flexure strength of beam which is composite saction and beamg
which is high quality saction.
