Abstract

In SNI 2847: 2013, the maximum reinforcement limitation requirement is no longer a constant
matter, but it depends on the type of reinforcing steel quality used in the design, because the
tensile strength of the tensile reinforcement steel ε_t ^ o in the condit ions of the nominal
flexural strength must be greater or equal to 0.005.
In SNI 2847: 2013, the reduction factor value ∅ is determined based on the tensile strain value
in the outermost fiber that occurs, ε_t ^ o (Net Tensiile Strain, NTS). It can be explained that
the value of ∅ is distinguished by the time of the compression controlled section, the tension
controlled sect ion and the transit ion area. If ε_t ^ o≤ε_y then the cross sect ion is said to be
pressure controlled and the value of ∅ = 0.65, when ε_y <ε_t ^ o <ε_t then the section is in a
transition state and the value of Ø = 0.65 + (εt- (ε_t) ̅) (250 / [(0.005- (ε_t) ̅) × 100]}, and when
ε_t ^ o≥ε_t the cross section is said to be tension controlled, the value of ∅ = 0.9, with ε_t =
0.005.
The tensile failure section has a good degree of ductility, for the column section it occurs when
the eccentricity value of the axial force, e, is greater than the eccentricity value of the axial
force under equilibrium, eb. The rational analysis step is to do the trial and error method
The purpose of this study is to guide the design of the flexural and axial compression
reinforcement area which is in the tensile failure category when the compressive reinforcement
has melted as required by SNI 2847: 2013 with a simple step, two-sided reinforcement.
This study method basically reprocesses the basic formulas of reinforced concrete column
cross-sectional strength theory in the previous author and SNI 2847: 2013 in order to obtain
another formulation that can be used in general with the aim of making graphics that can be
used as a tool to simplify and simplify the design. the area of bending reinforcement. The study
has produced a general formulation and graphs that can be used for all types of steel grades and
concrete grades less than or equal to 28 MPa.
