Hint for problem 3.6-3

Posted on by

Note that for T’s cut from W and S shapes, the Manual for Case 8 on page [16.1-28] states:

bf >= (2/3)d … etc. and

bf <= (2/3)d … etc.

The d is for the parent shape, not d of the T section.

Show why, but try an ST9x27.35/

Hint for problem 3.4-4

Posted on by

To calculate U for a wide flange bolted in the web, Segui says that since you haven’t yet discussed a plantic neutral axis, just use Case 7 on page [16.1-28] in the manual.  However, since he forgot that there weren’t 4 bolts along the load axis, that case does not apply.

Thus the simplest thing to do is just do what the manual says, and we will explain plastic neutral axis concepts later.

The manual says on page [16.1-28] to use case 2. But that doesn’t help since I don’t know what he means by Xbar on the figure.

That’s what the commentary is for.  Since we are having trouble applying Part 16, Chapter D3 in the Specifications [16.1-28] we will go get help from the corresponding section in the Commentary on page [16.1-282].

Note that it is critical that you see what just happened.  We went to the same Chapter D3 in the Specifications to D3 in the Commentary.

 

Here he says exactly what to do for this case on page 16.1-284:

Now do I really understand all that?  Not really, at least not yet.  Do I clearly understand what the manual says to do?  Absolutely.  I simply go to page [1-22] where information on a W16x40 is listed, find the Zy = 12.7 in^3 and the cross sectional area A = 11.8 in^2 and calculate Xbar = 1.076″.

I also, as a practical engineer I check to see if I think this is reasonable by noting that the flange width = bf = 7″ wide and thus sticks out about 3.5″ from the neutral axis.  From the above calculations the manual is making me say the centroid of the unconnected flanges is pretty close to half of how far they stick out.  That’s probably reasonable, since the centroid of the flange alone would be about 3.5/2 = 1.75″, and the web area draws the centroid back in towards the axis of symmetry of the W shape.

Hint for problem 3.3-5

Posted on by

To calculate U for a W connected by 2 plates bolted or welded to the top and bottom flanges:

Xbar for the wide flange = Ybar for a tee cut from that W shape,.  For example, for a W12x120, you cut it along an axis of symmetry down the loaded length of the W into two WT 6×60 sections.  Then you get Xbar for the W (the distance from the flange face to the centroid of the unconnected element – the web) by using the distance from the WT 6×60 flange face to its centroid, denoted by Ybar in the manual.

Thus, if you have a W12x50 bolted or welded on the top and bottom plates with 5 bolts in a line where the bolts are spaced 3″ apart (down the load axis), Xbar will equal:

      U = 1 – Xbar/L = 1 – 1.17″/12″ = 0.9025

where the 1.17″ is the Ybar from the flange face to the centroid of a WT6x25 on page [1-64] and the 12″ = 4 bolt spaces at 3″ each.

Final Exam Schedules

The final exam will be open textbook (Segui, open AISC Steel 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.

The final will cover everything in the course.

You are also permitted to bring a copy of the Steel section, Fundamentals of Engineering Reference Manual.

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 may well 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 wheelchair and having the wheel fall off, veering me into oncoming traffic.  That may be justice served, but I’m not having it.

STRUCTURAL STEEL DESIGN
Course Syllabus – Spring 2018
MWF 9:10 – 10:00 am (Sec 502, 10702)
MWF 1:50 – 2:40 pm (Sec 503, 24559)
HEB (Old CE Building) Room 219

PLEASE NOTE: The syllabus will suffer changes throughout the semester, depending on our ability to cover the material. Please check the syllabus daily for changes, especially before you work any homework problems, which are subject to change.

Help for CVEN 446 is available from the people shown below, at the office hours listed.

Professor: Lee L. Lowery, Jr., PhD, P.E.

Office: DLOB (7th floor of Dwight Look Office Building)
Room: 705e
Phone: 979-845-4395 (Office), 979-775-5401 (Home)
e-mail: Lowery@tamu.edu

Tentative Office Hours (subject to being called out by the boss or having to go to an unannounced meeting)

Much of my time is spent teaching two sections of CVEN 446, one section of 305, and ENGR 485. During the remaining hours I advise and have office hours as listed above.  Please plan on assistance either during my office hours, or from the Teaching Associate below. Please don’t wait until just before class or a quiz to get help or you likely won’t get any.

I try and keep my calendar up to date, and to add unexpected meetings as they arise, but when the boss drops by and says let’s go, I go.  So please call before you come by, even if you have an appointment, unless you are already in the area.

Teaching Associate:  Cesar Barron Castro

Click here for instructions on purchasing this manual. NOTE that you MUST be registered in CVEN 446 (Lowery) this semester to use this coupon code. You can pay online, or by mail, and they will ship the book directly to you. The price shown is greatly reduced from anything you can get elsewhere. Upon request I will e-mail your coupon code to you. Please note that they have issued only one code for students in our sections.  Please do not give it to anyone else (your mom, etc.).  We only have codes for students in our class. If someone else uses your code it won’t be easy to get another one.  Once you have your code, please follow the instructions above.  E-mail your request for your code to Lowery@tamu.edu using the subject line: AISC code request, Your Name and Student ID.

Textbook: Because different sections are using no text, or Segui, or Geschwindner, I really don’t care which text you get, but the homework problems will come out of Segui 6th edition.  The information in all texts is comparable.  Get whichever you like, but I strongly recommend that you get something.  Don’t go without a text if at all possible.

CHECK HERE FOR EXAM DATE:

Final Exam Schedules
SPRING 2018 ONLY

The final exam will be closed book, open AISC Steel Manual with handwritten added notes. No textbook or loose notes permitted. You can add any handwritten notes on the last blank pages in your LRFD Manual. These can include example solutions or anything of your choice.

You must also bring a copy of the Fundamentals of Engineering Exam Reference Manual, Steel Design section. Click here for a copy.

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 me in 20 years.

Chances of making what grade in Lowery’s 446 class after Quiz A, and after Quiz B

Posted on by

This might help you decide if you should Q-drop the class

After Quiz A
Your probable final grade in Lowery’s 446 Class was:
A B C D F
If your
Quiz A
grade
was:		 A 68% 29% 3% 0% 0%
B 29% 50% 19% 2% 0%
C 6% 48% 38% 6% 1%
D 2% 27% 57% 14% 0%
F 0% 7% 52% 34% 7%

For example, a student who got a D on Quiz A had a 27% chance of getting a B in the class

After Quiz B
Your probable final grade in Lowery’s 446 Class was:
A B C D F
If your
Quiz
(A+B)/2
grade
was		 A 98% 2% 0% 0% 0%
B 43% 55% 3% 0% 0%
C 3% 67% 29% 2% 0%
D 0% 8% 79% 11% 2%
F 0% 4% 37% 52% 7%

For example, a student who got a D average on Quiz A + Quiz B had a 8% chance of getting a B in the class
