Abstract

The length of reinforced concrete blocks varies widely, while in general the
reinforcement produced in Indonesia is 12 m. Therefore, the use of reinforcement in a long
stretch is done to be connected. The through connection is the most economical connection [2]
.
Lap splice can be made by overlapping the reinforcement which is touching or separate [3]
.
Splicing reinforcement can cause the strength of reinforced concrete beams to be reduced or
even damaged so that rehabilitation measures are needed which can be in the form of retrofit
(repair). Retrofitting with wiremesh and self compacting concrete (SCC) is considered to
improve building structures. Reinforcement overlapping on reinforced concrete beams retrofit
with wiremesh and self compacting concrete can be analyzed by numerical methods to determine
their effect on bending behavior. Now, to analyze a structural behavior, it can be done using
finite element method based program. The application of the finite element method is used in
several programs, including ABAQUS, ADINA, Atena, ANSYS, etc. This study aims to analyze
the overlapping of reinforcement in retrofit reinforced concrete beams against the flexural
behavior, overlapping is made at one-third and one-third of the beam span using finite element
method based analysis software.
