Computing Project 1: Using a frame analysis software (MASTAN or its equivalent)
Two frame problems will be set for the students to analyse. They will be asked to provide a report based on all the work carried out for the analyses and the assumptions made. They will be asked to present results in the form of graphs and diagrams (shear force, bending moment and deflection) and their interpretation of the results obtained.

Computing Project 2&3: Two small projects using the commercial FE package ABAQUS
Students are required to submit Tutorials 2 and 4 of Segment 2. They will be asked to present results in the form of graphs, interpret results obtained and answer specific questions.
