Question

The truss shown consists of horizontal and vertical members made of aluminum (E = 70 GPa) and the others made of steel (E = 210 GPa). The cross section areas are 60 mm2 for the vertical members, 100 mm2 for the horizontal member, and 75 mm2 for the diagonal members. Determine the vertical and horizontal displacements of Point B using Castigliano’s Theorem.

The final answer for the deflection in the y,v = -23.457 mm

And for the x,u direction is = 7.348 mm

I want the right steps and equations for the question

Explanation / Answer

Steps are

1)calculate dead load,self weight,wind load.

2)reaction at the ends of structure.

3)calculate bending moment.

4)torsional effect.

5)moments acting on the horigentol and vertical member.

6)find displacement
