| dc.description.abstract | Reinforced-concrete requires bending and shearing reinforcement. Bending reinforcement is used to detain
bending moment, whereas shearing reinforcement (sengkang) is used to detain shearing load. Generally, vertical
shearing reinforcement has a function to detain shearing load. Whereas horizontal shearing reinforcement is not
calculated in detaining load force occured on a beam. Vertical shearing reinforcement prevents a beam to apart due to
shear force. This research was done to find whether horizontal shearing reinforcement (alternative reinforcement) is
required in construction. The objectives of this research is to know the maximum shear load and the difference between
alternative reinforcement and conventional reinforcement in reinforced-concrete beam. This research was carried out in
5 steps, i.e., preparation of research equipment and material; inspection of research material quality; provision of test
materia; concrete strength compression test and reinforced-concrete beam shear compression test; and analysis and
discussion. The research took place at Construction Material Laboratory at Civil Engineering Department, Faculty of
Engineering UMS. The number of object test were 12 pieces, and 2 pieces of object test were used for each variation. The
space variation used were 40 mm, 80 mm and 120 mm, with reinforcement weidth 15 cm and height 20 cm, and beam
length 150 cm. According to analysis result, it is known that maximum shear force occurred in a reinforcement with
space 40 mm, i.e., 1797,7 kgs for conventional reinforcement and 1735,2 kgs for alternative reinforcement. Whereas,
maximum shear compression is 766,5 kgs for conventional reinforcement and 704 kgs for alternative reinforcement, and
the biggest difference between conventional reinforcement shear compression and alternative reinforcement shear
compression is 28,31% which occurred in a reinforcement with space 80 mm, and the difference of shear load is 8,49%.
Generally, it can be said that shear strength between conventional reinforcement and alternative reinforcement is
relatively equal. | en_US |
