Description

Direct stiffness method of analysis; static and kinematic condensation; non-uniform torsion; geometric and material nonlinear analysis; rigid-plastic analysis; dynamic analysis of multiple-degree-of-freedom systems

This course covers advanced topics related to the development of discrete linear and nonlinear models of structural systems, and the application of matrix structural analysis techniques to numerically simulate the deformations and internal forces induced in them under the action of static and dynamic loads.

The material covered in this course builds on introductory analysis and systems concepts covered in ENCI335: Structural Analysis and Systems 1. This course will develop important analytical skills required to succeed as practising structural and geotechnical engineers, and also develop the necessary foundational knowledge in preparation for more advanced postgraduate level courses such as ENEQ623: Finite Element Analysis of Structures and ENEQ624: Nonlinear Structural Analysis and Dynamics.

Learning Outcomes

1. Develop linear and nonlinear numerical models of structures by making appropriate assumptions and idealisations.
2. Evaluate the deformations and internal forces induced in structures under the action of external static and dynamic loads, and internal self-straining loads, by conducting linear and nonlinear analysis.
3. Interpret the simulated structural responses in light of the precision of the analysis results and the quality of the model idealisations.
4. Assess the stability of structural systems by evaluating their critical buckling loads and buckling mode shapes.
5. Evaluate the ultimate strength and deformation capacities of structures beyond their initial yield point using the statical and mechanism methods of rigid-plastic analysis.
6. Compare and contrast the responses of structures predicted using linear, nonlinear, static, and dynamic analyses, and comprehend the limitations of each type of analysis.

University Graduate Attributes

Your course grade will be decided based on your total course score, which is computed as the
weighted average of your scores in the following three components: assignments, a midsemester
test, and a final exam.

Assignments
• You can expect about 80% of your learning to occur while working on the assignments; hence, you are strongly encouraged to begin working on them early, and to ask plenty of questions during the tutorial sessions and office hours.

• You are advised to diligently review all the relevant lectures before attempting the assignments, in order to get the most out of them.

• The assignments will require you to relate new concepts with those discussed in earlier courses, and to explore beyond the material covered in the lectures, in order to adequately prepare you for life beyond your undergraduate studies.

• You may work on the assignments in pairs and submit one solution for which both you and your partner will receive the same score. You must create/join a Learn group before you can submit an assignment solution. If you choose to work in pairs, it is expected that both you and your partner work together on all parts of all problems, and do not just divvy up the work among yourselves.

• You are permitted to discuss the problems with other students, but are not permitted to copy their work. The solutions you submit should reflect your own understanding of the problem, organisation of the calculations, and interpretation of the results.

• Assignment solutions must be submitted as a single PDF file on Learn; hardcopies will not be accepted. Handwritten solutions must be scanned using a scanner. If a scanner is not available, the CamScanner app may be used to edit and combine photographs into a single PDF file. It is your responsibility to make sure your solutions are legible.

• Since this is a professional engineering course, it is expected that the submitted assignment solutions are neat and well organised. Marks will not be awarded for incoherent, untidy, or illegible submissions.

◦ Sketches and free body diagrams must be included where appropriate. They must be neatly drawn either digitally or using a pencil and ruler.
◦ Graphs must be plotted using a computer. They must contain axis labels, units, ticks, grid lines, and a legend where appropriate.

• Assignment problems will be marked on a scale of 0 to 3 based on the following criteria:
◦ Completeness: Have reasonable attempts been made to solve all parts of the problem?
◦ Concept: Does the solution reflect an understanding of the underlying concepts?
◦ Execution: Have all the intermediate steps, formulations, and calculations been
presented in a neat and orderly manner?

The marking scale is defined as follows:
◦ 0 (Poor): No solution or less than 20% in completeness, concept, and execution
◦ 1 (Average): Between 20% and 50% in completeness, concept, and execution
◦ 2 (Good): Between 50% and 90% in completeness, concept, and execution
◦ 3 (Excellent): Above 90% in completeness, concept, and execution

• You are given a total allowance of two late days for the entire course, which you may use for the submission of assignments. Submission of an assignment at any time up to 24 hours late will result in the deduction of one entire late day, and so on.

Test and exam
• They will test your conceptual understanding of the course material, as well as your ability to solve problems.
