This report analyzes the effectiveness of epoxy jointed steel bar laps for bending
capacity of RC beams. The objective of this study was to determine the pullout
strength of different epoxy jointed steel laps length and to determine the flexural
strength of epoxy jointed lap in RC beam with the most optimum lap length using
Universal Testing Machine. Standard steel bar size of 12mm diameter and concrete
mix proportion of l(cement):2.33(fine aggregate):3.5(coarse aggregate) with a
water/cement ratio of 0.55 were applied throughout this study. As the material of
study, high strength adhesive for bonding reinforcement from SIKA called Sikadur-
30 was used. The development of tension laps length were 10 O (120mm),
15 <3> (180mm) and 203> (240mm) by which the epoxy jointed beams were compared
for its strength to continuous tension steel reinforcement beams. With the optimum
lap length obtained for epoxy jointed steel bar lap, construction error due to
shortened lap length designed could be rectified andsteel wastage at construction site
could be minimized by joining two to three steel bars of insufficient length together
to produce one continuous steel reinforcement.
