Abstract

Studi kasus perilaku lentur  balok beton bertulang dengan penambahan serat tali beneser  dilakukan secara eksperimental. Benda uji yang digunakan berupa balok. Ukuran penampang benda uji balok adalah 100 mm x 150 mm dengan panjang 1400 mm. Tulangan longitudinal yang digunakan adalah tulangan polos berdiameter 10 mm dan tulangan geser yang digunakan adalah tulangan polos berdiameter 6 mm. Sedangkan serat tali beneser yang digunakan memiliki panjang 50 mm dan ukuran tampang 1.5 mm x 0.58 mm. Variasi benda uji ada 3 dengan masing-masing variasinya dibuat 2 balok dan 3 silinder. Pada variasi pertama digunakan substitusi serat tali beneser 0% dari volume beton. Variasi kedua dengan substitusi serat 0,6% dari volume beton. Variasi ketiga yaitu beton dengan substitusi serat 0,9% dari volume beton. Penambahan serat mampu menambah kapasitas beban dan mampu menahan lendutan lebih baik. Kapasitas beban ultimit dan lendutan BN,BS 0.6% dan BS 0.9% masing-masing 41.293 kN, 39.993 kN, dan 44.226 kN, dengan lendutan sebesar 20.239 mm, 17.428 mm, dan 16.744. Daktilitas BS 0.6% dan Bs 0.9 % terhadap  BN dengan rasio 0.73 dan 0.74. Kekakuan BS 0.6% dan BS 0.9%  terhadap BN sebesar 0.83 dan 0.93.

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.
