PENGARUH VARIASI JARAK TULANGAN SENGKANG MIRING DAN VERTIKAL TERHADAP KUAT GESER PADA BALOK BETON BERTULANG Abdurrahman Muhadzdzib Atthariq, Budi Kudwadi 1), Ben Novarro Batubara2) Program Studi Teknik Sipil S1, Fakultas Pendidikan Teknologi dan Kejuruan, Universitas Pendidikan Indonesia Email : [e-mail] ABSTRAK Balok merupakan salah satu elemen struktur beton yang sering digunakan. Balok seringkali menerima gaya lentur, torsi dan geser, sehingga memerlukan tulangan utama dan sengkang. Salah satu cara untuk menahan gaya geser dengan cara penggunaan tulangan sengkang vertikal atau sengkang miring, atau kombinasi sengkang vertikal dan sengkang miring. Kombinasi sengkang miring dan sengkang vertikal pada balok dapat meningkatkan kuat geser. Penelitian ini menggunakan 12 buah balok beton bertulang ukuran 120 mm x 160 mm x 3000 mm dengan 3 buah balok beton bertulang dengan tulangan sengkang vertikal (BSV) dan 9 buah balok beton bertulang dengan kombinasi tulangan sengkang miring dan vertikal dimana dari 9 balok tersebut memiliki 3 variasi jarak sengkang miring dengan jarak 100mm(BSMV1), 120mm(BSMV2) dan 140mm(BSMV3). Benda uji menggunakan tulangan pokok 4Ø10mm dan tulangan sengkang Ø100mm dan diteliti tentang beban maksimal yang mampu di tahan, defleksi, dan gaya geser. Pengujian pembebanan pada alat uji universal test frame ditumpu pada sendi dan rol dibagian ujungnya, dan dibebani 2 beban terpusat pada 1/3 bentang. Pembebanan diberikan secara bertahap dengan interval kenaikan sebesar 50 kg menggunakan hydraulic jack hingga baloknya runtuh. Hasil dari penelitian ini menyatakan balok beton bertulang tipe BSMV1 mampu menahan gaya geser terbesar sebesar 400 kg dengan lendutan mencapai 1,208 cm, balok tipe BSMV2 mampu menahan sebesar 350 kg dan lendutan 1,206 cm, balok tipe BSMV3 sebesar 300 kg dengan lendutan 1,146 cm, dan balok tipe BSV menahan gaya geser sebesar 300 kg dengan lendutan yang terjadi mencapai 1,206 cm dengan demikian maka balok tipe BSMV1 lebih baik dari BSMV2, BSMV2 lebih baik dari BSMV3, dan balok tipe BSMV3 lebih baik dibanding balok tipe BSV terhadap keruntuhan geser.

Beams often accept bending, torsion and shear forces, so that they require the main reinforcement and stirrup. One way to hold the shear force is by using a vertical stirrup or oblique stirrup, or a combination of vertical stirrup and oblique stirrup. The combination of angled stirrup and vertical stirrup in the beam can increase shear strength. Resource uses 12 reinforced concrete blocks of size 120 mm x 160 mm x 3000 mm with 3 reinforced concrete blocks with vertical stirrup reinforcement (BSV) and 9 reinforced concrete blocks with a combination of angled and vertical stirrup reinforcement where of the 9 blocks have 3 variation of angled stirrup distance with a distance of 100mm (BSMV1), 120mm (BSMV2) and 140mm (BSMV3). The specimens used the principal reinforcement of 4Ø10mm and stirrup reinforcement of Ø100mm and were examined about the maximum load that is able to withstand, deflection, and shear forces. The loading test on the universal test frame is supported on the joints and rollers at the edges, and is loaded with 2 loads centered on 1/3 span. Loading is given in stages with an increase interval of 50 kg using a hydraulic jack until the beam collapses. The results of this study stated that reinforced concrete beams of type BSMV1 were able to withstand the largest shear force of 400 kg with deflections reaching 1,208 cm, beams of type BSMV2 were able to hold by 350 kg and deflection of 1.206 cm, beams of type BSMV3 amounted to 300 kg with deflections 1.146 cm, and beams BSV type withstands shear force of 300 kg with deflection that occurs reaches 1,206 cm so that the BSMV1 type beam is better than BSMV2, BSMV2 is better than BSMV3, and BSMV3 type beam is better than BSV type beam against shear collapse.
