Abstract: The use of headed stud shear reinforcement has been widely accepted as an effective strategy to improve the punching shear resisting performance of reinforced concrete (RC) flat plates. In order to study the shear behavior of a group of shear studs placed on a composite beam, a total of 16 pushout tests were conducted, including 4 specimens with cast-in-place (CIP) concrete decks and 12 specimens with precast concrete (PC) decks. The procedure to determine the key characteristics of the wedge block is established. Spacing 4 times diameter between studs in plane perpendicular to the shear force and 6 times diameter in the direction of the shear force is generally adequate to develop full. The stud diameter and yield strength have a significant effect on the shear behavior of studs. The cross-sectional area of a ¾-in.

As the bolt head is tightened, the cone is pulled up the bolt thread, causing the legs of the sleeve to expand until the cone locks the sleeve against the inner wall of the. (7/8″)22mm. 6. 12. The first parameter is the yield stress of stirrups where its effect on the punching shear is studied by using stirrups with different yield stresses of 240 MPa and 420 MPa. The first step towards the design recommendation is to understand the difference between the headed shear studs and the bolted shear connectors in a push-out test. This moment caused tension in the headed shear stud closest to the actuator, impacting the overall shear strength of the studs. The reduction factor, k t is obtained from Equation 6. A total of 102 push-out tests were carried out on standard test specimens with varying parameters including concrete types (normal weight, lightweight and ultra-lightweight), concrete strengths, and types of J-hook connectors. 13 H4L 205 101-053-010 studs in a plane perpendicular to the shear force and six H 16 H4L 68 101-053-012 times diameter in the direction of the shear force is generally 16 H4L 106. Download scientific diagram | Steel plate with shear stud details from publication: The Effect of Steel Plates with Shear Studs for Weak Column–Strong Beam Connections in the Reinforced Concrete. For Series 1, one connection did not have shear reinforcement, while the other two connections had ribbed-deformed GFRP shear studs with headed ends at different radial spacing (120 and 80 mm). From these studies, a coefficient for the shear resistance of stud (∝3) is derived and will be considered for studs in unfavorable position in the new procedure for the calculation of shear.

(2016) 23: 2676í 2687 2678The end studs are set in the width of adjacent wall studs, and sheeting extends to cover adjacent wall ends and meet at external corner. This paper intends to study the load sharing mechanism between the shear studs and sheeting in push tests through the. Ancon Shearfix Punching Shear Reinforcement is used within a slab to provide additional reinforcement around the columns. Lower shear strength of the concrete-concrete interface will cause the interface cracking of the push-out specimen, which occurs before the stud. 6dstud < 12 in.
