For the frame and design loads shown in Figure 1, determine the moment amplification factor
?s for all the columns. The beams are 360UB45 sections and the columns are 310UC158
sections. All beams are rigidly to the columns. The column-to-footing connection is pinned.
All beams and columns are bent about their major axis.
Question 2 – Beam-column design and check (65 marks)
Check the adequacy of a 200UC46.2 of Grade 350 for columns (A-1) and (A-4) shown in
Figure 2. Ignore the self-weight of the beams and columns. All beam-to-column and beamto-shear wall connections in the east-west direction and in the north-south direction are pinned.
All column-to-footing connections are also pinned. All columns are fully restrained only at
the base and top of the second storey (roof level). A uniformly distributed permanent action
(dead load) of G = 20 kN/m and an imposed action (live load) of Q = 8 kN/m is acts on all
beams in the east-west direction and a uniformly distributed wind load of Wu = 3 kN/m acts on
the flange of column (A-1) as shown in Figure 2 Details of the simple connections in the eastwest direction are given in Figure 2.
The minimum eccentricity requirement according to Clause 4.3.4 of AS4100 for simple
connections only in the east-west direction should be considered.
The columns are subjected to axial compression and uniaxial bending about their major axis.
