Does the column shown in the figure have enough availablestrength to support the given service loads?a. Use LRFD.b. Use ASD.
Need complete and elaborate solution A.Using ASD, check the adequacy of the base plate (PL400x350x19 mm) centered on a W12X152 column as shown. It is resting on a concrete pedestal that is 450 mm x 400 mm. The loads are PDL = 600kN and PLL = 320 kN. Use A-36 steel and concrete fc’=20 MPa. B. Using LRFD, PL400x350 mm base plate, W12x120 column, 500x500 mm pedestal, PDL = 1200 kN and PLL = 800 kN. Use A-50 steel and concrete fc’ = 30 MPa. Determine the required base plate thickness.
