STUDI PEMODELAN BERBASIS FEM BALOK BETON BERTULANG MENGGUNAKAN LUSAS 14.0 YANG DIPERKUAT DENGAN GFRP

In this era, has developed improved methods of repair and retrofitting for
structure with matrix or binder, known as Fibre Reinforced Polymer (FRP). Research
on the behavior of reinforced concrete beams retrofitted by GFRP previously have
been done in the laboratory. However, laboratory results can’t provide the complete
information or data because the limited ability of the tools and testing methods. To
get the accurate experimental results of the test, we need more specimens and it will
be need much money. To overcome this problem, we try to modeling based on Finite
Element Method (FEM). The research method that we used is a simulation
laboratory using LUSAS 14.0 based of finite element method. The test results then
compared with the results of laboratory testing. The test results using the program
LUSAS 14.0 shows that the result is similiar with the result of laboratory. If we
comparison with the normal beam that reinforced concrete beams without refrofitted
by GFRP, it would show that the reinforced concrete beams retrofitted by GFRP
will give increase the capacity of the receiving load beam is equal to 36%. LUSAS
modeling results also show the distribution of strain that occurs in the steel
reinforcement and GFRP along the span. Given the more load on the beam, will
increase the strain of steel and GFRP of the end to the middle of the span and the
maximum strain occurs in the loading area.
