______________
• this is a “closed book examination” except the Student is allowed to bring in the
CSA-S16-
01
CISC
Handbook of Steel Construction (9
th
Edition) but not
the Class Notes
. Calculators are permitted but
not
any other computational aids or electronic devices which transmit, receive, record or replay, etc.
• cross-reference all answer sheets to the questions and hand these in with your exam.
•
answers/calculations are complete only if the numbers are accompanied by units.
•
draw and use sketches freely to explain and support your calculations.
•
use the
Tables
in the Handbook to your advantage.
•
units are [
mm
] and [
MPa
] unless noted otherwise.
•
the exam consists of 4 questions (not all equal marks) and 6 pages for a total of 100 marks.
Question 1
(30 marks)
:
Cantilevered Beam with a Welded
Connection
A 4-metre long
W310x74
(
W12x50
) steel cantilever beam is welded to a “rigid support”
with an
E49xx 8mm
fillet weld all-around as shown in
Figure 1
.
Section properties for
the member are given in the
Handbook
on page
6-52
.
The steel grade is “50 ksi” with
,
F
y
=345 MPa,
F
u
=450 MPa.
Draw a free-body diagram for each of the load cases below, and according to
CSA-S16-
01
, assign to each load case the maximum load which you would permit on this member:
a)
axial load P
x
?
b)
lateral load P
y
?
c)
vertical load P
z
?
d)
torsional moment
(torque)
M
xx
?
how is this torque carried along the length of the
beam? sketch the shape of the torque-carrying mechanisms and label each one.
