Question
[STRENGTH OF MATERIALS (10.9)] Please provide a solution to the problem. The answer is already given just provide a solution. Thank you! ANSWER: bending is limiting, and gives an allowable superimposed load of 45 kN/m; required welds 0.26 cm throat thickness.
A compound girder consists of a 45 cm by 18 cm steel joist, of weight 1000 N/m, with
a steel plate 25 cm by 3 cm welded to each flange. If the ends are simply-supported and
the effective span is 10 m, what is the maximum uniformly distributed load which can
be supported by the girder? What weld thicknesses are required to support this load?
10.9
Allowable longitudinal stress in plates = 110 MN/m?
Allowable shearing stress in welds = 60 MN/m?
Allowable shearing stress in web of girder
= 75 MN/m?
