School of Engineering – Civil & Environmental Engineering Final Year Theses Project Planning Document All parts of this document are compulsory, and until it has been completed and approved, you will not be permitted to undertake any work on your project. There is no single component of assessment for this form, because the amount of information required will vary from project to project; however, your Method Statement, Risk Assessment and overall Project Planning will influence the general assessment of your thesis. Please complete the form, save and print it out and obtain the relevant signatures. Then submit it in the appropriate submission box at the ETO. One document per student, even for groups of two. Name of Student: • •

I have consulted with my Supervisor: If your work will involve a workshop or laboratory check here

to confirm you have consulted with the relevant lab manager.

Project Planning Document for Civil & Environmental Engineering Thesis Projects – Version 2, October 2011


Introduction Provide a brief overview of your project, indicating the problem you are investigating and the main aims and objectives. It is accepted of course that plans change which is why you will review this document in your interim submission due in January.

The use of potted resin anchors in high tensile structures such as suspension bridges is becoming relatively well established, despite the fact that there is little understanding into how these assemblies perform in a fire. Aim: To investigate and quantify the performance of high tensile steel potted resin anchors in fire. Objectives: • Test potted resin anchorage assemblies until failure, in a controlled thermal environment while subject to axial tension. • Create a computer model that can give concordant behaviour with experimental observations. • Comprehensively conclude on the performance and possible ramifications of our findings for contemporary and future anchorage assemblies. • Theorise on how our findings affect the overall performance of structures and advise on any improvements that may be required to minimise potential failure.

• Method Statement The Method Statement is an overview of how you expect to conduct your project. It serves multiple purposes: • Helps you think through all the steps required to complete your project. • Acts as a discussion document with your supervisor and technical staff. • The Method Statement is used to identify items that need to be included in your Risk Assessment, Resource Planning, and Schedule of Work (below). The Method Statement is the first thing to be written, because it identifies the items that need to be considered below. Provide an overview of how you expect to conduct your project. Consider, amongst other items, the stages of your project, potential hazards of the work involved and the resources that will be needed. The project mainly involves the experimental testing of the steel wire and anchorage assemblies in a hydraulic tensile testing machine with a thermal oven. Prior to testing •

Compile the Project Planning Document and conduct a Literature review

• •

Source the materials for testing, and gain specifications on size and strength from the manufacturer Prepare the materials for testing (assemble if necessary – see document on Rope Cable Terminations)

During Testing •

3 by Axial Strength Test of wires to determine failure load (stated as 111kN for 12mm wire but it is thought to have strength ~550kN). Varying Stress/Strain with Time.

4 by Resin Socket Test at each of the following strengths related to ultimate strength found in previous test; 10%, 20%, 30%, 50% and 90% (i.e. 20 tests in all). Load constant in each test, vary Temperature with Time. Measure Strains/Failure and Temperature of Resin with thermocouple.

Note: Thermal Load (curve) needs to be defined. Ideally try to simulate a real fire situation, therefore use rapid heating of sample – 10°/min. Further test options involve the modifying of the heating curve – not included here, possibly outside realistically attainable scope. •

Any un-failed, cooled assemblies (perhaps the 10% won’t fail), will be tested to destruction and the residual strength compared to the initial tests. If all tests are deemed to have failed, the fire load curve could be modified for a couple of extra tests so this behaviour can be studied.

After Testing • •

Tidy up the experiment before repeating any if necessary Start work on a computer model of the experiment

Summary of resources needed This section must indicate with as much detail as possible the physical as well as human resources that you need for your project, as well as costings. It is essential that this is discussed with your supervisor so that any necessary approvals for materials/equipment and requests for technical help can be made early on in your project.
