Unformatted text preview: and at the centroid of the crosssection. Ignore the selfweight of the beam in your calculations
Assume weldpair centroids follow the of the W310 crosssection (i.e 31016.3= 294mm).
. Figure 1 (page 2/6) CE 470: Final Exam (12 April 2010) –Structural Steel Design Question 2 (40 marks): BEAMCOLUMN
The W460x177 beamcolumn shown below is 20metres high with lateral supports at
the top and bottom. It is preferable to minimize bracing about the weak(yy) axis and
therefore, the crosssection has been reinforced with a pair of S380x74 members which
are bolted to the flanges of the W460 sufficiently to achieve an integral/composite crosssection as shown in Figure 2; yy bending is laterally suppressed at midheight.
The reinforced beamcolumn carries biaxial end moments and an axial load.
Secondorder analysis with notional loads for P (sway) and P (curvature) effects
provide the end moments below. Assume there are no transverse loads on this column.
● about the xxaxis, the beamcolumn is attached to a roof truss and is part of a...
