The purpose of this study is to investigate the ultimate strength,
load-slip characteristrics and mechanical behaviors of shear
connectors. The experimental tests were made using 12 push-out
specimens with deformed bar shear connectors. The concrete strength
of Fc=210kg/cm2 was used in the tests.
Based on the tests and the analysis of the results, the following
conclusions were made :
1. The characteristic strength of shear connector may be taken
as Pu=0.4 a/ay-0.6a/ay.
2. The maximum load was reached when a slip value of each
specimen was between 4-6mm.
