Instructions: For the beam below, design the beam using trial section W21x147. If the section is insufficient, select other properties from the W21 table to satisfy adequacy, local buckling, design capacity, shear, and deflection. Use the LRFD method. Lateral bracings are found at supports. Also, use A36. For the deflection in our laboratory, use the service load combination = DL + LL for LRFD Also, utilize the W21x147 section property has Zx = 6110x10^3 mm3 and Zy = 1520x10^3mm3 in addition to the table that is found on the following pages. LL = 60 KN/m DL = 50 KN/m (Excluding self weight) A 8.00m

select other properties from the W21 table to satisfy adequacy, local buckling, design capacity, shear, and
deflection. Use the LRFD method. Lateral bracings are found at supports. Also, use A36. For the deflection in
our laboratory, use the service load combination = DL + LL for LRFD
Also, utilize the W21x147 section property has Zx = 6110x10^3 mm3 and Zy = 1520x10^3mm3 in addition to
the table that is found on the following pages.
