Transcribed Image Text:

The figure shows the upper half of a built-up girder (the cross section is symmetric about the neutral axis). All rivets used in fabrication have a diameter of 22 mm. The moment of inertia of the entire cross-sectional area of the girder about the neutral axis is I = 4770 x 100 mm. The working stresses are 100 MPa for rivets in shear and 280 MPa for bearing of the web plate. If the maximum shear force carried by the girder is 450 kN, determine the largest allowable spacing of rivets that join the angles to the web plate. 10 mm: 510 mm 300 mm- 10 mm 18.9 mm -A=2430 mm Web plate 1000 mm x 10 mm ---NA FIG.
