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 Shear strength degradation of 7.9 - 13.7% for specimens with full height sti ffener comparing to non - stiffened shear connectors and 14.2 - 26.6% for those specimens with half height stiffener. Full height stiffener has increased in shear strength between 157.1 - 233.1% and half height stiffener has increased in shear strength between 4 5.1 - 150.6% under monotonic loading. These ranges were between 161.8 - 305.4% for full height and 19.0 - 225.1% for half height stiffener under fully reversed low cyclic fatigue loading. Generally, specimens with stiffeners.
