Abstract: “An experimental study was performed to investigate the behaviour of a newly prop osed shear connector named as stiffened angle shear connector. The connector is proposed to fulfil the deficiency of angle shear connector based on previous researches have been conducted by the authors [1 - 3] . The co nnector has been tested experimentally under monotonic and fully reversed low cyclic fatigue loading. In each series, four push - out specimens were tested covering different sizes of stiffened angle shear connector and different types of loadings. Later the comparison of the shear connectors’ performance in the case of with and without stiffener has been conducted. The results show not adequate ductility of newly proposed shear connectors, but much better performance in case of shear strength. All specimens have the connectors’ fracture type of failure since high strength concrete has been chosen to cause this fracture for better investigation. The newly proposed shear connector showed She”
