PENGARUH PERKUATAN GESER FIBER REINFORCED POLYMER TERHADAP BEBAN DAN LENDUTAN BALOK BETON

Abstract

Fiber Reinforced Polymer ( FRP ) is a material that is lightweight, strong,
antimagnetic and corrosion resistant. This material can be used as an option to
replace steel as reinforcement material in the construction of reinforced concrete
or as material to add strength to existing construction. This study aims to
determine: the behavior of the influence shear strengthening fiber reinforced
polymer toward load and deflection concrete beam in the structure by the method
of FRP reinforcements on the outer side of a sheet of woven carbon fiber. The
shape and spacing of windings, namely: winding method U with the distance of
each winding 50 mm and 150 mm . This study begins with a tensile steel ( fy ), the
test characteristics of aggregate , concrete mix design f'c = 25Mpa, making
concrete cylinders Ø = 15 c, t = 30cm, curing and compressive strength test 28
days. Furthermore, to analysis beam, sheets of woven carbon fiber. Then given the
test object beam shear reinforcement in the form of woven carbon fiber sheets by
the method of winding U with the distance of each winding 50 mm and 150 mm.
Shear strength capacity test is done with concrete beam flexural test. The maximum
load for the results of this study of normal concrete beams, FRP U-50mm, U150mm
respectively were: 67 kN, 70KN, 70KN and deflection were: 1.94 mm, 2.94
mm and 2.79 mm.
