PENGARUH JARI-JARI KELENGKUNGAN HORISONTAL BALOK TEPI BETON BERTULANG TERHADAP BEBAN DAN LENDUTAN
ABSTRACT:
During this
time civil engineers
design horizontally curved
reinforced beam in
field using straight
beams approach. The design
codes of horizontally
curved reinforced concrete
beam didn’t exist in
SK SNI T-15-1991-03
and ACI but there is code about horizontally curved steel i.e AASHTO
Guide Specifications for Horizontally Curved Highway Bridges (1980).
This research follows
up the research
that has been
done by Hsu
(1974) about intersection
structure between straight spandrel and floor beam. The speciment which
were used in this research were straight spandrel beam and spandrel
beam with horizontally
curvature 3,3147 m
(curved8 spandrel beam)
and 4,80695 m
(curved12 spandrel beam) and 1 every speciment. Loading was done on floor
beam statically with increment 1 kN gradually. The support on spandrel beam
is hinge but torsionally
fixed and on
floor beam is hinge
too. To investigate
behavior of spandrel
beam speciments hence LVDT, inclinometer, strain gauge are installed.
The results of research are displacement on first crack load higher
if spandrel beams
are curved. Displacement
on quarter span
are displacement curved8
spandrel beam >curved12 > straight. Tension bending
reinforcement are yield.
Keywords: nonlinear, spandrel beam, horizontally curved reinforced
concrete beam
