Design static strength of a stud shear connector.

Design code	Shear strength model
AASHTO LRFD [11]
	where and : design and nominal shear strength of a stud; : resistance factor which can be taken as 0.85; : cross-section area of a stud; : compressive strength of concrete; : elastic modulus of concrete; : ultimate tensile strength of a stud.
Eurocode-4 [12]
	where : design shear strength of a stud; : depends upon the height-to-diameter ratio, is taken as for and 1 for ; : partial factor which can be taken as 1.25.
