4 points An angle bar with equal legs with 17.1 mm thickness used as tension member is connected with 20-mm-diameter bolts. Both legs of the angles are connected. The pitch distance
between two staggered bolts center to center is 50 mm and the distance of the bolt on both legs from the corner of the angle 62.5mm. use Ag = 2,079 mm^2,
Fy = 248 MPa and Fu = 400 MPa. Determine the critical effective net area of the angle in mm^2. Express in 2 decimal places. [Show Less]
