The given girder has beams framing into it at the ends and at every L/3 point. The
beam carries a service live load of 20 kips as shown and superimposed uniformly
distributed service dead load of 10 kip/ft. Select the lightest A992 W-section that
can carry the load. Do not check for deflection.

A rectangular beam reinforced for both tension and compression barshas an area of 1450 mm² for compression bars and 4350 mm² fortension bars. The tension bars and compression bars are placed at a distance of 600 mm and 62.5 mm respectively from the top of thebeam. The beam width 300 mm, fc’ = 21 MPa, fy = 415 MPa andtension steel covering is 60 mm.If it is 8 m-simply-supported beam that carries three concentratedservice live loads P applied at three quarter points of the beam (exceptat the supports), neglecting the self weight of the beam, determine themaximum value of service load P in kiloNewtons.
Determine whether a W24 x 117 of A992 steel is adequate for the beam shown. The uniform load does not include the weight of the beam. Lateral support is provided
