High compression loads are well sustained by concrete elements, while tensile loads are poorlyrntolerated. Therefore, reinforcing steel bars of various standard sizes and lengths are used for therndesign of reinforced concrete structures. Manufacturing, fabrication, and transportation limitationsrnmake it impossible to provide full length continuous bars in some reinforced concrete structures.rnFor this reason, it is often more convenient to work with shorter bar lengths, it is frequentlyrnnecessary to splice bars in the field. Lap splices cause congestion at the splice locations, sometimesrnmaking their use impossible; rebar congestion making it difficult to concrete to pass through; thernindustry has also used mechanical coupler splice generate rebar splices. There are many types ofrnmechanical splicing products available in the world, in Ethiopia threaded coupler use somernconstruction project at Addis Ababa. The objective of this research is to study the speed ofrninstallation procedure among splice type, cost of splice type, the splice to be used, load-deflectionrnand crack behavior of reinforcement concrete beams under static point load configuration ofrndifferent reinforcement splice type. The methodology is experimental program, and it has beenrnperformed to investigate the research tested in point load configuration with cube test of concreternand tensile test of reinforcement splice bar type. Each beam was designed to include two bars inrntension, spliced at the center of the span. A total of twelve beam specimens, specimens wererngrouped into four groups to investigate influences of splice type with respect to control beam, weldrnsplice beam, lap splice beam and mechanical coupler splice beam. Each series was involved threernbeams tested to investigate the performance of reinforcement bar splice type. The findings of anrnexperimental investigation, cost comparison and installation for reinforcement splice type statedrnunder the objective with short summary. Recommendations are presented at the end.
