Abstract

ABSTRACT The connection of reinforcing steel is accomplished because the length limitation of production and condition. Regulations have not recommended explicitly or prohibit a particular kind of connections. The use of mechanical connections configuration and the lap splice connections were developed in this study. Reviews of research are not only including technical aspects of strength and integrity of structural elements, but also observe the ease of manufacture and implementation. Research program is conducted by reviewing the configuration of lap slice length and the amount of clamp which has been used. The research of connections is reviewed in conditions of bare bar which embedded in concrete beams. The bare bar conditions did as if reinforcement tensile test, which the variable is the number of clamp with a lap splice configuration 1clamp+lap splice 6,34db and 2clamp+lap splice 6,34db. Application of the connections is made through 5 kinds of bending beam specimen which its reinforced connections is made on appeal bar diameter (db) = 16mm, the variable of joints is lap splice 6,34db, 1clamp+lap splice 6,34db, 2clamp+lap splice 6,34db, 2clamp+lap splice 19,016db , and it as a control beam without connection. Concrete quality, steel quality, and tightening boults of clamp are fixed variables. The research has resulted clamp force which increased significantly sized up ± 100 % of its number, the most optimum number use 2 clamps, the strength of lap splice raise keep up with its length. The minimum configuration is best used 2 clamps with length minimum of lap splice 11,41db. The stiffness of five specimens indicated high equivalence with R² = 0,931 but the ductility of bar with lap splice connection 6,34db is not equivalent compare with bar without connections, it’s only 22%. From the result of research, we can conclude that the connection variant has a huge potential to be used, however it still needs to be re -observed because it still has weakness of its ductility, next the subsequent research needs to be carried out by improving the quality of clamp material with the most optimum length of lap splice.
