Behavior Of Concrete Beam Deflection Framework System

Abstract

The bar used for concrete beams is generally in the form of shear or stirrups mounted perpendicular to the beam axis. The idea underlying this editorial problem arises from the writer's observation of the use of reinforced concrete beams by changing the configuration of vertical shear reinforcement to less sloping reinforcement related to the theory of its use. This study aims to analyze the deflection behavior of reinforcing beams with a three-quarter spacing distance from the effective height of the beam and produce the bending moment capacity of the skeletal beam reinforcement system. This research is an experimental laboratory study with twelve specimens consisting of three normal beams (BN) as control variable beams and nine reinforcement beams with a frame variation of 0.25d for BTR25, 0.50d for BTR50, and 0,75d for BTR75 each of the three test specimens. Data were analyzed using the strength design method. The results showed that the use of reinforcing frame systems could increase the strength of the beam when the load reaches the ultimate in the BTR25 beam by 10.72% for the BTR50 beam by 7.83% and for the BTR75 beam by 4.82% from the BN beam.
