Assignment brief

Guidelines for assignment submission

1. There is one Assignment and individual progresses as shown in the Key Milestones.

1. Each assignment/Presentation has its own submission date. All the tasks have to be submitted by the dates specified in Key Milestones. The first 5 reports should be submitted to the module leader and only the final report need to be submitted to the moodle.

1. All the LOs MUST be submitted on time to be considered for a MERIT grade.

1. The final assignments will be subject to PLAGIARISM PLAGIARISM is a serious academic offence and will automatically lead to ACADEMIC MISCONDUCT PROCEDURES.

1. The attendance percentage and participation in class will contribute towards the achievement of Distinction grade.

1. Each student in the GROUP needs to submit his / her own contributions to the project by the deadlines specified. All students should take part in the presentation.

Glossary

Analyse: Break an issue into its constituent parts. Look in depth at each part using supporting arguments and evidence for and against as well as how these interrelate to one another.

Compare: Identify the similarities and differences between two or more phenomena. Say if any of the shared similarities or differences are more important than others. ‘Compare’ and ‘contrast’ will often feature together in an essay question.

Evaluate: Give your verdict as to what extent a statement or findings within a piece of research are true, or to what extent you agree with them. Provide evidence taken from a wide range of sources which both agree with and contradict an argument. Come to a final conclusion, basing your decision on what you judge to be the most important factors and justify how you have made your choice.

Discuss: Essentially this is a written debate where you are using your skill at reasoning, backed up by carefully selected evidence to make a case for and against an argument, or point out the advantages and disadvantages of a given context. Remember to arrive at a conclusion.

LO4 Be able to apply design methods

Explain the following concepts which are essential in producing valid designs for all the aforementioned structural members:

3. Limit State Design
4. Ultimate Limit State
5. Serviceability Limit State
6. Actions
7. Permanent Actions
8. Variable Actions
9. Accidental Actions
10. Partial safety factors

Try to also clarify your definitions by using diagrams or case studies as well as explaining in your own words the importance of each of these concepts to the design of the structural members.

Eurocode 2 and 3 sets out the Basis for structural design of structural members including steel beams, steel columns, reinforced concrete beams, reinforced concrete columns, and etc.

Beam Design

A simply supported beam is shown in Figure 4.1. This example demonstrates the design of a simply supported beam. The beam is 8.0 m long. In this example, it is assumed that the floor slab does offer lateral restraint. Using EC2 and EC3 regulations, design the beam assuming RC or steel section.

Compare the cost of structure using both designed cross section.
