Calculation: “G” + .038 = .163 + .038 = .201 Stud Dash Number Selected From Table: -6 Complete Part Number: 2600-6S Stud Dash Number for ultrasonic installation. Integral stud cup protects top panel surface from abrasion. 2600 Series. Previous researchers have proposed various definitions for the shear stiffness prediction of welded stud connectors. Oehlers and Coughlan [ 2] proposed an empirical equation to calculate the initial shear stiffness of normal stud connectors based on the experimental results, as shown in Equation ( 4). It is adopted by Shim et al. [ 16] to evaluate the shear stiffness of large diameter studs, and the results show that Equation ( 4) gives rather conservative predictions:

Shear stiffness comparison between the equation prediction and the test value. 4.3. Evaluation of Peak Slip Much earlier, Buttry [ 27] put forward a fractional formula for the load-slip curve of conventional welded stud connectors: The International Federation for Structural Concrete [ 26] suggests the following equation to calculate the peak slip of welded stud connectors: Shear stiffness and peak slip distribution for four groups of push-out specimens. 4. Evaluation of the Push-Out Test Results 4.1. Evaluation of Shear Strength damage. Select the ejector spring corresponding to stud assembly series selected. See table for part numbers.

Insert stud into panel and release when cross pin RS PRO is our own brand range and brings you a wide range of high-quality, great value products offering you more choice. Trusted by engineers all over the world, every part of every RS PRO product has been rigorously tested against demanding industry standards; they’re only given the RS PRO Seal of Approval if we’re confident of their exceptional quality, which means you can be confident too. Provides for retraction of stud assembly to allow opening and closing of equipment without the possibility of jamming or GB 50017 [ 23] provides Equation ( 3) to estimate the shear strength of welded stud connectors: where is the characteristic compressive strength of concrete prisms (MPa) and other variables have the same meaning with Equation ( 1). In GB 50017 [ 23], the resistance factor or the partial factor for the shear strength of welded stud connectors is not clearly specified.

In this paper, push-out tests are implemented on four groups of welded stud connector specimens, including conventional and high strength 22 mm stud connector specimens and 25 mm and 30 mm stud connector specimens. The shear strength of these welded stud connectors is investigated and compared with the prediction of the design equations recommended in AASHTO LRFD [ 19], EN 1994-1-1 [ 18], and GB. The shear stiffness and ductility of these welded stud connectors are also examined and compared with the estimation by the existing equations. In addition, the applicability of load-slip relationships for conventional stud connectors to large diameter and high strength stud connectors is also discussed. 2. Experimental Work 2.1. Push-Out Specimens In Equations ( 8) and ( 9), is the slip value of welded stud connectors (mm) and stands for the ratio of the loading force to the shear strength of welded stud connectors. Lin et al. [ 24] proposed a semi-theoretical equation for predicting the shear stiffness of normal stud connectors based on the theory of a beam on an elastic foundation and ninety-nine test results collected from the available literature, as shown in the following equation:holes. Can also be installed in tapped holes. Blind end version is ideal when receptacle is to be used with structural

Peak slip comparison between the equation prediction and the test value. 4.4. Evaluation of Load-Slip Curve EN 1994-1-1 [ 18] specifies the design strength of one stud connector given by the following equation: where is the diameter of the stud shank (mm), which is specified between 16 mm and 25 mm, is equal to 1.0 when the overall stud height is larger than four times of its diameter, the tensile strength of the stud material is specified no greater than 500 MPa according to EN 1994-1-1 [ 18], the recommended value for the partial factor is 1.25, and other variables have the same meaning with Equation ( 1).
