Transcribed Image Text:20. The framing plan shown in Figure P2.20 is for an 18-
story office building. It must support a dead load of 80 psf
and a live load of 50 psf. In all cases, the decking spans in
a direction from line A toward line E. Determine the
required moment and shear strength for the beams and
girders, and axial strength for the columns, as required
below for (a) design by LRFD and (b) design by ASD.
Calculate with and without live load reduction, as
appropriate.
i. The beam between column lines 2 and 3
along line D.
ii. The girder on column line 3 between
column line E and midway between lines D and
C.
iii. The beam on the line between lines C and
D and column lines 3 and 4.
iv. The column at the corner on lines 1 and E
that supports eight levels.
v. The column on the edge at the intersection
of lines 4 and A that supports eight levels.
vi. The interior column at the intersection of
column line 4 and the point midway between
lines C and D that supports three levels.
