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

holes. Can also be installed in tapped holes. Blind end version is ideal when receptacle is to be used with structural select stud dash number, then subtract seven dash numbers. Requires .438 diameter installation hole. Solid rings are used to hold stud assemblies stationary to the top panel. Split ring allows stud assemblies to move Compress stud assembly spring using Camloc pliers, P/N 4P3, as shown. Insert stud into panel and release when cross pinBoth the 30 mm stud and the high strength stud exceed the limitation of current design codes, so the applicability of the existing design equations to large diameter and high strength studs need to be evaluated. In AASHTO LRFD [ 19], the design strength of one stud connector can be determined by the following equation: where is the nominal shear strength of the welded stud connector (N), is the cross-sectional area of stud shank (mm 2), is the elastic modulus of concrete (MPa), is the characteristic cylinder compressive strength of concrete (MPa), the nominal tensile strength of welded studs is 415 MPa, and the resistance factor for welded stud connectors equals 0.85. 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.

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: To be used as a guide only. To obtain optimum performance, final hole size should be determined for Ultimate tensile strength: 300 lbs. Working strength: 200 lbs. Stud grip increments: .030 inch.
