A small one-story reinforced-concrete building shown blow is idealized as a massless frame supporting a total dead load of 10 kips at the beam level. Each 10-in.-square column is hinged at the base; the beam may be assumed to be rigid in flexure and E = 3 x 103 ksi. Determine the peak response of this structure to ground motion characterized by the design spectrum above scaled to 0.25g peak ground acceleration. Determine the displacement at the top of the frame and the bending moments in the two columns.

Q4) Two considerations have been proposed for the design of a beam as shown in Figure (3). Determine which one is the best to support a moment of M-150 kN.m according to the bending stress. Figure (3) Wam

Concrete T-beam has been reinforced by bonding a steel plate to its web asshown below. The beam carries a uniformly distributed load of 40kN/m over a simply supported 8m span. Find the maximum deflection of the beam on the assumption that the concrete is fully operative in both tension and compression.(Est = 200kN/mm^2. Econc = 30kN/mm^2; central deflection due uniformly distributed load, total W acting on a simply supported beam of span L= 5WL^3/(384EI)) can someone please answer this question in detail who is confident in this topic with step-by-step calculations & sketch pls. I've asked this question twice now and I've gotten different answers each time so I'm at a bit of a loss. (DONT respond to this if you have already responded previously) Thank you
