Assignment 4 (T2-2018) Design report and presentation (Individual submission)

This outline must be read in conjunction with the “Project description and specifications”

Submission due on Week 11 Thursday 5:00 PM (AEST), 27 September 2018

General information

Students shall commence working on their design project from the very start of the trimester. All required knowledge relevant to material properties, basic actions on structures and the structural response to resulting stresses will be thoroughly discussed during classes and studio sessions (Bb collaborate sessions for cloud students). Students will go through a design project that resembles practical engineering exercises. As part of the project, mechanical and functional properties of a wide range of materials will be discussed during studio sessions, classes as well as practical sessions. Students shall make rational design choices considering engineering, cost-effectiveness and relevant environmental sustainability aspects. Students shall be encouraged to propose alternative/ innovative solutions for their design project based on relevant research.

Description of the assessment task

This assessment task forms the final outcome of the design project and should be read in conjunction with the “Project Description and Specifications” document uploaded in the unit site (Resources Project information). Following table lists the structural elements assigned to each group to propose a suitable preliminary design

• solution. Please refer to Figure 3 as shown in “Project Description and Specifications” document. Students shall

Learning resources

Practical design aspects covered during project studio sessions will be directly aimed at assisting students to achieve a suitable solution for the given project. Theoretical knowledge taught during classes and relevant examples covered during unstructured studio sessions will provide a strong base for appropriate understanding of the subject matter. “Design” is always an open-ended task; there are always alternative solutions to any given

• task. Justification of the design choices made during a design process plays a key role in the

final design proposal, which must be justified by rational arguments. Additional useful study resources relevant to the project will be made available in due course through the unit site accessed via DeakinSync.

Submission requirements

This is an individual submission but students will work in groups to achieve their proposed design solutions. The report must be no more than 5 pages (excluding the title page) and all pages must be numbered. Use size 10 Calibri or Arial fonts with single spacing for your report. Relevant Figures/ Graphs/ Tables must be reasonable in size (maximum 12 cm wide × 10 cm height) Every student shall submit the following 2 files in Assignment 4 folders - Design report (PROJECT) and Video presentation (PROJECT) on the Unit site accessed via DeakinSync.

• 1. An electronic file containing the final report (no more than 5 pages and all pages must be numbered).

The file should be named as “Surname_First name_Student No_Assignment 4_design report_SEJ103”.

• 2. A video file containing short video presentation (no more than 3 minutes) containing the highlights

and outcomes of the design project. The file should be named as “Surname_Firstname_Student No_Assignment 4_video presentation_SEJ103”

Evaluation of students’ performance

Assignment 4 is designed to assess Unit Learning Outcomes (ULOs) 1, 2 and 3 as students will have to apply subject specific knowledge and have to communicate within their assigned groups to achieve a suitable design

• solution. These ULOs are mapped to partially achieve Graduate Learning Outcomes (GLOs) 1, 2, 3 and 4.

Students’ performance will be evaluated using a rubric. Feedback on your performance and grades will be published once a lecturer appropriately assesses student submissions – both the report and the video

• presentation. This evaluation process will take approximately 2 weeks after all reports are submitted.

This assignment contributes a total of 35% towards the final grade. The technical report will contribute 25% and the remaining 10% will come from the video presentation.

Outline of the Design report (25%, individual submission)

The design report should be no more than 5 pages (excluding title page). Every student must prepare a report, which clearly explains the scope, the significance and the outcome of the project in her/his own words. The report shall include clear and concise calculations, concise written sections and neat sketches in appropriate scale, if required. Students shall submit electronically typed reports but free- hand neat sketches may be used in the report if required.

3 Students must use SI units at all times. Appropriate references to design codes (with sufficient details to clause/ table/ figure) and other sources (including web sources) must be clearly cited in the report. Tables, figures and charts are useful tool in technical report writing, and students are encouraged to make use of those techniques in an appropriate and effective manner. Following are some guidelines on the content of the design report. Students are welcome to use these guidelines as a reference but are highly encouraged to present in their own way.

• 1. Title page

On the first page of the submission, every student must include the following items:  Unit code and unit title  The title of the assignment with assignment number  Student name with Student ID and Group number

• 2. Project brief

In their own words, every student is required to clearly explain the scope of the project highlighting the key tasks that form the very core of this assignment. The structural elements that are assigned to each student must be clearly identified using appropriate sketches and/or notations; physical significance, if any, of this relative location should be clearly highlighted.

• 3. Design of Column

3.1 Materials used for compression Outcomes of a brief research activity to identify materials that are typically used to design structural elements subject to compression should be presented in a clear and concise manner. Students are encouraged to use tables and/ or graphs to compare different materials and to make rational judgment

• n their choice(s). Mechanical properties, cost effectiveness, environmental aspects are few of a long

list of criteria that could play vital role in making an appropriate material choice for the design task. Final material choice(s) must be clearly mentioned supported by rational information and/or evidences. 3.2 Calculation of design load for the specified column All calculations based on the tributary area concept and loads taken from the relevant AS/NZS code must be briefly presented in a neat and clear manner with appropriate references. The basis for the calculated factored design load should be clearly mentioned with reference to the relevant design clause. Adopted load intensities for imposed actions and calculated self-weights of structural elements must be clearly mentioned. All relevant references and assumptions must accompany required calculations. 3.3 Proposed column section The proposal(s) made for the column section must be supported by justified arguments from design perspectives such as cost of material and maintenance, ease of construction, availability of the material, significance of the structural shape etc. A neat sketch of the proposed section(s) with required material specifications are required as the final design proposal. Students making innovative design decisions with appropriate justification will be given special commendation for their efforts.

• 4. Design of Beam

4.1 Calculation of design load for the specified beam All calculations based on the tributary area concept and loads taken from the relevant AS/NZS code must be clearly presented in a concise manner using neat sketches. All relevant references and assumptions must be clearly mentioned. 4.2 Determination of design bending stress Critical section(s) along the span must be clearly identified and the corresponding bending stresses should be determined; underlying assumptions, if any, should be clearly mentioned. The variation of bending stress on the critical section must be investigated and presented to support your decision in choosing an appropriate cross-section. 4.3 Selection of material and type of cross-section Students will be encouraged to explore all possible cross-section and material types made available to them to obtain an optimum solution for their specified beam. Please beam in mind that there is no absolutely perfect solution in design; you have to justify your choice with rational arguments. Your chosen cross-section must be presented with a neat sketch accompanied by the material specification. 4.4 Transverse shear and its (possible) effect on your design Clearly present the variation of shear force along the beam span, identify the critical section (or sections) and determine distribution of shear stress on the critical section(s). Check if your chosen section is capable of withstanding the resulting stress(es). Students are encouraged to propose modifications to their chosen cross-section if there is room for making it even more efficient (based on the knowledge you gained in SEJ103). Students coming up with innovative ideas will be given credit for their efforts. However, clear identification of any possible limitation to the proposed design will be seen as a positive contribution. 4.5 Final design for Beam The final proposal(s) made for the beam section must be presented with a neat sketch and all supporting justifications should be mentioned in a concise manner.

• 5. Summary

Concluding remarks as you see appropriate

• 6. References

All references must be listed and should be appropriately cited in your report; this is an essential part of any technical report.
