Question
Looking to get help calculating #7.

Transcribed Image Text:1. Determine whether a W14x90, A992 column with a
length of 12.5 ft is adequate in a braced frame to carry the
following loads from a first-order analysis: a compressive
dead load of 100 kips and live load of 300 kips, a dead
load moment of 30 ft-kips and live load moment of 70 ft-
kips at one end, and a dead load moment of 15 ft-kips and
a live load moment of 35 ft-kips at the other. The member
is bending in reverse curvature about the strong axis.
Determine by (a) LRFD and (b) ASD.

Transcribed Image Text:7. Reconsider the column and loadings in Problem 1 if
that column were bent in single curvature by (a) LRFD
and (b) ASD.
