Question
The frame shown below is unbraced against sidesway. Assume that all columns are
W14 x 61 and that all girders are W18 x 76. ASTM A992 steel is used for all members.
The members are oriented so that bending is about the x-axis. Assume that Ky = 1.0
%3D
a) Use the alignment chart to determine Kx for member GF. Use the stiffness
reduction factor if applicable. For member GF, the service dead load is 80 kips
and the service live load is 159 kips.
b) Compute the nominal compressive strength of member GF.
