Part 1 The simply supported beam below is initially designed to undertake a concentrated factored live load of 45 kips (215 kN). Assume that the beam is laterally supported and the self weight neglected. Use: A992 steel (Fy= 50 ksi or 345 MPa) E = 29 x 10® psi (200 GPa), the maximum allowable deflection Aall = L/360 45 kips 16 ft 16 ft 1/ Determine the most economical W shape beam required Part 2 The most economical selected beam from Part 1 ends up being subjected to a concentrated live load of 20 kip. Determine the corresponding maximum live load deflection. Part 3 Assuming that the beam will only be braced laterally at the supports and every quarter spam points (8ft from each support), verify whether the chosen cross section still checks under the live load of 20 kips only. If not, what are your design recommendations?

Q2) The members of the truss structure shown below is plain concrete. The compressive strength of the concrete is 25 MPa. Compute the maximum load P that can be carried by the structure.

HOMEWORK-1 Зт IF For the truss shown in the figure; a) Calculate the bar forces for F=4000 kg. b) Design members 1-2 and 2-3 assuming that out of plane deflections are restrained and Aer>>10, i.e. global buckling is not the critical failure mode and therefore linear static analysis is sufficient. P.S. Use square rectangular hollow sections in Grade 355 steel. You will have to find the related section tables from the internet. Do not forget to refer to the related EN1993-1-1 tables and equations. Later, you will design the connections (the weld lengths, etc.) and the supports for this problem.
