Extracted text: Problem #1 A W 10 x 45 is used as a beam with two lines of 19 mm diameter boplts in each flange using A 36 steel. There are at least three bolts in each line and the bolts are not staggered with respect to each other. Use LRFD Method. Prop. of W 10 x 45 A = 8581 mm? d = 256.54 mm bf = 203.71 mm tr = 15.75 mm tw = 8.89 mm Fy = 248 MPa Fu = 400 MPa O Determine the effective net area that can be assumed to resist tension of the section through the holes. Ae = U An U = 0.90 ® Determine the design strength due to fracture in the net section where bolt or rivet holes are present. ø = 0.75 ® Determine the design strength due to yielding in the gross section which is prevented member. inteded to excessive 203.71 mm elongation of t 0.90 I- 15.75 mm d=256.64 mm 15.75 mm
