- Concrete strength = 4,000 p.s.i. - No additional reinforcement in the concrete has been assumed in the analysis of the sharktooth inserts. - Headed welded studs utilize a design factor of 2:1, as per manufacturers recommendations. - Insert #ST-3 and #ST-4 allowable shear loads and tension loads are controlled by headed stud strengths. - Insert #ST-6 thru #ST-C working tension and working shear loads controlled by insert flange bending. - Combined loading evaluation using;

- Allowable loads shown are applicable along the entire length of insert, no minimum distance required. - Minimum edge distance to centerline of headed stud equals 3-1/4” (vertical installation). - Minimum concrete required above or below centerline of headed studs, when mounted vertically or horizontally is 3-1/4”. - Higher allowable loads can be achieved for the #ST-3 or #ST-4 insert by increasing headed stud diameter.
