Structural Analysis

Section B (no workings required). Question 14 Figure Q14 shows a 1 metre long I-beam supported at either end. The symmetric I beam has dimensions 50 x 30 mm for the outer sections, and 25 x 30 mm for the middle section (width x height). The beam has a tensile strength of 300 MPa. Loading the beam in the middle and applying a Factor of Safety of 2.

Use the Moment Distribution Method to analyse the frame when subjected to the loading shown. Dimensions and load values, which depend on your student ID, are given in the table below. Determine the member forces and support reactions required in the table below. Enter your answers in the space provided.

Question 1. Determine the internal normal force, shear force, and bending moment acting at point C' in the beam.

Question 4. Determine the internal normal force, shear force, and bending moment in the beam at points C and D. Assume the support at A is a roller and B is a pin.

Question 5. Determine the internal normal force, shear force, and bending moment in the beam at points C and D. Assume the support at A is a roller and B is a pin.

Question 6. Determine the shear and moment in the beam as a function of x.

Question 9. Draw the shear and moment diagrams for the compound beam

Q2: Determine the Force in member 1-3 of the steel truss shown in Figure 2, using Force Method. The stiffness EA is the same for all the members.

Question 11. Draw the shear and moment diagrams for each member of the frame. Assume A is fixed, the joint at B is a pin, and support C' is a roller.
