Homework No. 13 切 This column is a part of an unbraced frame system. It is subjected to Pu = 550 kips and factored end moments M = 2700 kip-in and M2 = 3750 kip-in. Determine the adequacy of the column when: a.) It is subjected to gravity loads with sidesway considered as negligible. b.) It is subjected to wind load resulting in a sidesway factored moment M. = 2500 kip-in. The total loading of all interior and exterior columns in a single floor is EP, = 21 x 10 kips. EP. = 45 x 10' kips Given: . . • f. = 5 ksi • fy = 60 ksi Unbraced length, l. = 19' • d = 17.5" d'=d" = 2.5" • VA= 2.0 VB = 1.2 Ba=0.5 for both parts a and b 10 - #8 20" . 20"
