합성보에 있어서 이형철근을 사용한 Shear Connector의 내력에 관한 실험적 연구 ( An Experimental Study on the Strength of Shear Connectors using Deformed Bars in Composite Beams )

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.
