A six story building has a structural steel beam-column frame that is appropriately fireproofed. The columns are spaced 20 feet o.c. in one direction and 25 feet o.c. in the perpendicular direction. The governing building code specifies that the frame must be designed to withstand the dead weight of the structure plus a roof snow load of -- psf and a live load on each floor of -- psf. The dead weight of the roof is estimated to be -- psf, and each subsequent floor is -- psf. The unsupported length of the ground floor column is 20 feet, and the columns at the other floor levels are 16 feet. Loads highlighted in red will be different for each group. Refer to the second page for the loads to be used for your group. 1) Design a typical interior beam for the third floor and the first floor using the most economical W12 section at each level. (Design based on bending and check for shear and deflection).. 20 ROOF 6 16 16 16 16 161 251 25¹ 25 25¹ 5 10 11 d
