In addition to diameter and length, other factors such as the spacing and arrangement of shear studs also contribute to their effectiveness. The distance between each stud should not exceed certain limits to ensure uniform distribution of stress The distance between each stud should not exceed certain limits to ensure uniform distribution of stress The distance between each stud should not exceed certain limits to ensure uniform distribution of stress The distance between each stud should not exceed certain limits to ensure uniform distribution of stressshear stud sizes. This spacing is typically calculated based on the Eurocode or local building codes.
