According to the requirements of the AISC$-$Manual and specifications, the

design considerations which apply to members subject to both axial force and

flexure, are available in:

a$)$ Chapter D and part $5.$

b$)$ Chapter E and part $3.$

c$)$ Chapter $H$ and part $6.$

d$)$ Chapter F and part $3.$

e$)$ Chapter J and part $7.$

Wind and other lateral loads cause columns to bend laterally, and the columns

in rigid frame buildings are subjected to

even when the frame is

supporting gravity loads alone:

a$)$ Bending moments.

b$)$ Shear forces.

c$)$ Axial tension.

d$)$ Axial compression.

e$)$ Torques.

The required total flexural strength of a beam$-$column member must at least

equal the sum of the:

a$)$ first$-$order moments only.

b$)$ Second$-$order moments only.

c$)$ first$-$order and second$-$order axial loads.

d$)$ first$-$order and second$-$order moments.

e$)$ Non the above.

For frames braced against lateral translation. The symbol $(M_{nt}),$ is referred to

as:

a$)$ The first$-$order axial load.

b$)$ The second$-$order moment.

c$)$ The first$-$order and second$-$order moment.

d$)$ The first$-$order axial load.

e$)$ The first$-$order moments.
