Question

a) By using the slope-deflection method determine the moments at A, B, C and D and then draw the moment and shear diagrams. Assume the supports at B and C are a roller and A and D are fixed b) Use SpaceGass to determine the moments at A, B, Cand D. c) Compare the results by the two methods and provide a sensible discussions why they are/are not equal. El is constant. 2.5 kN 20 kN/m 4
