On MWF from 10:00 until our 446 class I will be preparing for class, so please don't expect help during those hours. Don't wait until minutes before class to get help or you likely won't get any. I try and keep my
calendar up to date, and will
try to add any unexpected meetings as they arise. |

AISC Steel Construction Manual 13th Edition only: Click here for instructions on purchasing this manual. Print out your receipt and take it to D'Anne or Susan in CE Room 140. NOTE that you MUST be registered in CVEN 446 this semester to pick one up. The book costs $120. Don't pay more for it anywhere.
LRFD Steel Design by William T. Segui: Thompson Brooks/Cole, 4th edition only - ISBN Number 0495244716
The Segui textbook is excellent - one of the best I have seen.

Assignment #40 due class #42 (Yep, class #42):
Design a single-plate shear tab for
45% of the shear capacity of a W
12 x 22. The beam is supported by a W14 x 53 column. Use 3/4" diameter (or larger if necessary), A325-N bolts and
E70XX electrodes as the fasteners. Assume A992 for the W-sections and A36
steel for the shear tab plate. Include a sketch of your final design with
proper notation. |

Final Exam will be held Wednesday, Dec 16th, 2009 from 10:30 a.m. to 12:30 p.m. CHECK THIS DATE FOR ACCURACY! |
The
final
exam will be open textbook (Segui), open LRFD manual with previous added
notes, no homework. You can
add up to 4 additional (12 total) handwritten 6"x9" pages (6 sheets
of paper total, written on 2 sides each) into the manual to supplement your
notes. It will cover everything in the course with emphasis on the material since the
last major exam. The distribution of material is planned to be approximately: 20%
Quiz A, 20% Quiz B, and 60% over the material since Quiz B. Please note that to pass this class you MUST be able design simple tension members to resist axial loads, to design beams to resist LTB, to design a column, and to design simple bolted or welded connections. These are minimum competencies. Things like combined bending and axially loaded members will likely be on the final, but being unable to do the simple things listed above will require that you find a better prof and retake this class. I simply cannot have you designing my old folk's home and dropping a beam on my head in 15 years. |
