Analyse the problem: Your team has been asked to design a steel
beam bridge with 10 m length
as a simple supported beam. The beam weight is 200 kN considered as
a distributed load over the
beam length. In addition, in the worst case, loaded trucks with an
average mass of 20 tons each will
pass the bridge, they can pass the bridge together or individually.
You only need to take the self-weight
and truck loads into account in your calculations. Hint: you can
consider two loads on the beam for
each truck or one load including the weight of both trucks.
Step 3. Consider the proposed loading condition.
Step 4. As a group of design engineers, you need to solve problems
and answer questions in
collaboration with your team members rather than individually! Make
sure to work as a team to
achieve the best result.
You will need to choose a 'Lead' engineer and the 'Supporting'
engineer for each requirement. The
roles are explained below:

(a) Determine the scenario that will create the maximum bending
moment and shear stress on the
simply supported beam.

(d) Decide on an alternative steel hollow square section with the loading condition specified in section (a) if the shearing stress is limited to 2 MPa. Discuss its difference with previous section in detail. Which section is your preference? Explain your reason. 5t 7.8t (e) Find the deflections of beam based on the worst-case scenario that you chose in part (a) above, and compare results. What is your judgement on the deflection? Is it acceptable or not?
