Title: Fatigue Strength of 3/4-Inch Stud Shear Connectors
Accession Number: 01055758
Record Type: Component
Abstract: Results of fatigue tests performed on seven steel-concrete composite beams are presented. The shear between the steel 24 WF 68 beams and the 6 inch thick slab is developed by means of 3/4 inch diameter headed steel studs. The beams were all identical except for the number of studs. The beams were 36 ft long and were divided into two groups: a. four commercially good and acceptable specimens and b. three inferior specimens not acceptable to the Texas Highway Department. Test results indicate: a. there is a difference (as much as 3 ksi) in fatigue strength between 1/2 and 3/4 inch studs; b. the American Association of State Highway Officials (AASHO) specifications allowable stress for stud shear connectors prudently could be increased by reducing the factors of safety present in use; c. two of the three defective specimens tested exhibited fatigue strengths equal to those of commercially acceptable specimens and d. for 10 million cycles the fatigue strength of the studs tested, expressed in terms of stress range, is at least 13 ksi.
