- Determine the design resistance to transverse force F,Rdarrow_forwardAs a structural engineer, your task is to design an optimum section that has sufficient resistance to the applied loading for the primary beam proposed in Figure 1. A UB in grade S275 steel is required for the unrestraint beam to carry the ultimate loads over the given span. Choose an optimumUB section and justify your selection. You are required to submit a design analysis by considering bending, shear, transverse force, and deflection checking for the selected member based on Eurocode 3 and the assumption of support condition and loading must be clearly stated.
