Formulate and execute relevant structural analysis using numerical modelling. Coursework Overview Steel is considered one of the environmentally friendly construction materials. It has a lower embodied carbon impact than concrete and is often reusable hence less waste. In the last decade, thin-walled steel beams have been widely used in structural, civil and aerospace engineering. They are commonly chosen to be structural components in residential, office and industrial buildings. Apart from the advantages of a steel structure, a thin-walled beam is a better choice compared to other beams with solid cross sections due to its high bending-stiffness-to-weight ratio. Thin-walled beams normally come in a variety of section shapes including I-sectioned, Z-sectioned and C-sectioned (channel) beams. However, due to its irregular geometry, the structural and mechanical responses of thin-walled beams are highly complex and shape-sensitive. Reliable numerical simulations to understand these responses are vital to the utilisation of steel materials. This leads to more efficient designs and better products with minimal waste helping to address sustainability and net-zero challenges. In this assignment, you will explore the load-bearing capacity of cold-formed lipped channel steel beams using a commercially available finite element software package (ABAQUS). The output will then be compared with a hand calculation approach. Coursework Tasks to be Completed by Students Figure 1 shows a simply supported cold-formed steel beam with a lipped channel section. The beam is subjected to two concentrated loads with the same magnitude of P. Straps are provided at the loading and support positions. The material properties include yield strength f₁ = 483.49 MPa, Young's modulus E=206.9 GPa and Poisson's ratio v = 0.3. b Dimensions h = 202.35 mm b=76.61 mm C 20.88 mm t = 2.4 mm P r = 5 mm 800 mm 1000 mm 800 mm 2600 mm Figure 1: Simply supported cold-formed steel beam. There are two main tasks that you need to do Task A - Numerically model in ABAQUS and determine the bending moment capacity (section moment capacity) of the beam section subject to local buckling. You will: • • • Describe the procedure of modelling the complex beam in the software with inputs are shown Visualise (plot) and comment on the relationship between applied load and vertical deflection of the beam Determine the bending moment capacity based on data from the numerical modelling Task B - Compare the computer modelling results with those estimated by the Direct Strength Method (hand calculations). You will: • Determine the bending moment capacity using Direct Strength Method (hand calculation) Compare and comment on the results estimated from the two approaches, numerical and hand calculations. MCE | Learning and Teaching Version 2.0 | Page 2 of 4 • How the numerical model or hand calculation approach can be used to make sustainable structural design reducing materials used and environmental impact.

If you become eligible to complete a Referral Attempt but are subsequently unable to undertake the opportunity when required, you will be permitted to re-sit the module at the next scheduled sitting of the module assessment. This will typically entail the suspension of your progression on your programme of study until such time that you have completed the level and become eligible to proceed.
