A composite beam system is composed of steel sections on which a reinforced concrete slab system has been attached. The 150 mm thick slab is concrete span lengths of 13 m and spacing of 3.5 m. The exterior beam has an edge with fc' = 28 MPa. The two-span beams with fixed exterior supports have distance of 0.85 m. The 20mm Grade 40 rebars in the negative moment regions are spaced center-to-center at 140 mm. The steel beams are A-50 W27x102. Full composite action is assumed.

3 COLLAPSE QUESTION A steel beam of l-section was reinforced by steel reinforcing plates welded to each flange. Some useful dimensions of the I-section and the steel reinforcing plates are given in Figure 4. The beam and reinforcing plates are made of elastic-ideally plastic material, with the yielding stress of oy. The second moment of area of the I-section (without the reinforcing plates) is known as I. i) If the moment applied on the section is M, derive an expression (in terms of oy, the dimensions given in the following figure, and ) for the moment when yielding just spreads each reinforcing plate (i.e., everywhere in the two reinforcing plates has reached the yielding stress, while the flanges haven't started to yield). ii) If the outer surfaces of the reinforcing plate (i.e., the top surface of the top reinforcing plate and the bottom surface of the bottom reinforcing plat) have just reached the yielding point, what is the stress on the outer surfaces of the I-section beam?…
