ENCV3ST: STRUCTURES 3

ASSIGNMENT 2 2015

This is a group assignment. Refer to e-learning for the group lists.

A portal frame to be used in a new warehouse is shown in Figure 1 below. All loads are factored and self-weight is to be neglected. The supports may be considered as fixed. Choose a suitable section size for the rafter and the columns (use Gr s355J structural steel sections) and proceed with the assigned tasks.

TASK 1

Using either SLOPE DEFLECTION or MOMENT DISTRIBUTION, determine the bending moment diagram, the shear force diagram, the axial force diagram and the reactions for the given loading. Draw the deflected shape, showing all deformations at the joints.

TASK 2

Using MATRIX METHODS and MATLAB, determine the deformations, the bending moments at all joints/supports and the reactions at the supports.

Draw the bending moment diagram, the shear force diagram, the axial force diagram and the deflected shape, using the results from your MATLAB routine. A short description of the limits of your programme must be included in your report.
