Analisis Balok Beton Bertulang Tampang T Yang Diperkuat Dengan Wire Rope Menggunakan Program Response-2000 Dan Metode Pias
Abstract: This study aims at
finding out the comparison of the results of analysis using Response-2000 and
discrete element method and of experiment on T-section reinforced concrete beam
strengthened using wire rope. The modeling was made on two T-section beams,
where one beam was without strengthening and another beam was with
strengthening using two wire ropes of 10mm. Results indicate that the ratios of
increase in flexural capacity as results of the analysis using Response-2000
and discrete element method compared to results of the experiment for the
control beam were 1.01 and 1.04, respectively, while the ratios of decrease for
the strengthened beam were 0.84 and 0.87, respectively. A ductility index for
the control beam as result of the analysis using Response- 2000 and discrete
element method decreased compared with results of the experiment with ratios of
0.31 and 0.60, respectively. A ductility index for the strengthened beam as
result of the analysis using Response-2000 and discrete element method
increased compared with results of the experiment with ratios of 1.19 and 1.92,
respectively. The ratios of increase in the initial stiffness as result of the
analysis using Response-2000 and discrete element method compared with result
of the experiment for the control beam were 2.85 and 3.33, respectively, and
the ratios of increase in equivalent stiffness as result of the analysis using
Response-2000 and discrete element method were 1.62 and 1.42, respectively. The
ratios of increase in initial stiffness for the strengthened beam as result of
the analysis using Response-2000 and discrete element method compared with
result of the experiment were 3.70 and 5.26, respectively, while those for
equivalent stiffness were 3.16 and 2.75, respectively.
