Problem 1) A composite floor system consists of W18x97 A572 Grade 50 steel beams spaced 7 feet apart.
The beams are 30 feet long and support a 5 inch thick reinforced floor slab of 4000 psi concre

Problem 1) Determine the maximum permitted tensile load Pu as limited by NSF ONLY,
for a pair of 5x3x1/2" angles bolted with A325 3/4" diameter steel bolts and loaded as
shown. Use 50 ksi steel.
Problem 2) Determine the maximum permitted compressive load

Problem 1) For the angle shown, determine the ultimate load as limited by Net Section
Fracture ONLY.

Rules: You MUST show all work in a neat and orderly manner. Please believe me when I
say you will be given no credit for work that I cannot follow at a glance. You may use
any design tables or aids, but you MUST reference exactly what page you are using t

If you feel any information required to work the problem is missing (and it may be,)
simply make an appropriate assumption for the missing data and state what your
assumption was.
1) For the 50 ksi 4x4x1/2" angle shown, determine
the maximum force applied

Please note that if I cannot follow your logic easily, you will get no credit for the solution, even if it is correct.
You MUST leave me 25% white space between calculations, for grading purposes. Further, if I cannot read
your writing, I will not grade t

1) The specially rolled shape shown is an 8" x 5" x 1" angle. It is rolled out of A242 steel and bolted with 1"
bolts. Determine the allowed dead and live load which can be applied in tension to the member, if the ratio
of Plive/Pdead = 4. If you see a mo

Problem 1) Determine the design axial strength ( Pn ) for the
W12x50 A36 steel column shown. The column is 16 feet long, is
pinned on the ends, and is braced at mid-height about the weak
axis. You may use any tables or design aids in the manual that

Problem 1) Determine the tensile load Pu which can be placed on the C10x30 channel shown. The holes were
drilled with a 1- inch drill. The channel is made of A242 steel. Check only the limit states for Gross Section
Yield (10 points), Net Section Fracture

Please note that the oldest trick in the book is to write so messily, and throw little calculations all over the page such that
your work is impossible to follow, hoping for partial credit. NOT. If your work is not presented in a neat and orderly
manner,
