Abstract


The bar used for concrete beams is generally in shear or stirrups mounted perpendicular to the
beam axis. The idea underlying this problem arises from the observation of reinforced concrete beams by
changing the configuration of vertical shear reinforcement to less sloping reinforcement, which would be less
relevant to the theory of its use. This study aims to analyze the skeletal system bending moment capacity
reinforcing beams and producing a theoretical equation of the bending moment of reinforcing the skeletal
system. This study is an experimental laboratory with twelve specimens consisting of three normal beams (BN)
as control variable beams and nine frame reinforcement beams (BTR) as independent variables. Data were
analyzed using the strength design method. The results showed that used reinforcement frame system increases
the beam strength when it reaches the ultimate load on the flexural capacity with the MPF frame retaining
moment on the BTR25 beam of 10.23%, the BTR50 beam of 7.47%, and the BTR75 beam of 4.60% of the beam
BN and found the equation for calculated the frame retaining moment (MPF). The equation can be used for
practical calculations of the retaining beam frame system (BTR).
