Lab Timetable See Lab Timetable: Two weeks after lab date Standard University scheme Aim: Enable students to understand the structural behaviour of aluminium and steel beams and learn how to conduct displacement and stress tests to obtain key data and characterise the structural performance. Learning outcomes: Understand the importance of evaluating displacement and stress in aluminium and steel beams adopted in construction Understand how displacement and stress tests can contribute to the evaluation of beam performance Design and conduct a test to evaluate displacement and stress Process experimental data from a structural test and compare them with theoretical evaluations Final Report: Structure of the lab report The lab report should be written as a professional report and follow five sections: Abstract, Introduction, Experimental work, Results and Discussion, and Conclusions. It is required to document your process, including: Assumptions Equations in variable forms Clearly drawn figures and diagrams Written description of the reason for each step Explanation of your answers/design choices A maximum of 10 A4 sides (11pt Arial minimum if typed) can be used. Marking Rubric 50% calculation accuracy 30% explanations and design choices 20% report layout Abstract Introduction Experimental work Results and discussion Conclusions Total Summary of the experiments (displacement and stress) and their outcomes Explanations of the importance of evaluating displacement and stress in aluminium and steel beams adopted in construction Explanations of how displacement and stress tests can contribute to the evaluation of beam performance Description of the equipment and material for the two tests Test setup and followed procedure Test 1 - for the three beam configurations: Theoretical evaluation of displacement with clear explanations Evaluation of the experimental displacement Comparisons between the theoretical and experimental values and reasons for their differences University of Liverpool - TQD Lab Test 2: Theoretical evaluation of stress Evaluation of the experimental stress Comparisons between the theoretical and experimental values and reasons for their differences Main conclusions Calculations 25 25 50 Design choices 5 10 10 5 30 Layout 20 20 2 Health and Safety Lab Procedures: 1. Students to be met by Supervisor and TA's outside relevant lab 2. Students should arrive at least 15 minutes before each lab session 3. While in the lab, students must wear appropriate PPE Personal Protective Equipment (PPE) Requirements ➤ Safety boots (with safety toe cap and sole) are compulsory in the lab ➤ If you are not wearing the appropriate PPE you cannot take part in the class According to the university policy, when the lab is rescheduled, the standard penalty of coursework capped at 40% will be applied. Emergency procedures Nearest exit route will be identified University of Liverpool - TQD Lab Fire alarm tests are undertaken: Harrison Hughes complex, Tuesday @ 11:00 Brodie Tower, Tuesday @ 10:00 George Holt, Tuesday @ 11:00 Albert Crew Centre, Thursday @ 10:30 The Assembly point: Harrison Hughes/George Holt - The quadrangle near the main entrance Active Learning Labs (mechanical engineering building) - The rear flagged area on Brownlow Street Brodie Tower - Outside the main entrance Albert Crew Centre - Outside the main entrance Please keep entrances/exits clear for emergency services and do not stand on the road Please keep your face masks on even when outside First Aid Should anyone require first aid assistance, please raise this with the TA or Technician General H&S requirements All students must abide by rules as set out by the TA or Technician, if any unsafe act takes place you will be asked to leave No food or drink allowed in labs or workshops If you see anything you think is unsafe, please make the TA or Technician aware Keep emergency exit routes clear at all times 3 TQD Test 1 - Displacement Aim: tks Figure 1: Equipment to measure the displacement Evaluate the displacement in the beam based on the applied load(s) Compare the experimental displacement with the theoretical one Displacement gauge Support E University of Liverpool - TQD Lab Beam THE Figure 2: Equipment details DAU Support 4 TQD Test 1 - Configuration 1 Simply supported beam with a central point load Aluminium beam Experiment 1.
