Paddington -
NCEES has had multiple tests which have been adopted by states which cover the practice of structural engineering. Currently the SE1 counts to the PE (mine is in MO too) and that is all. The SE1 is just an alternative the general civil or other PE exams.
Some states have a...
Use truss horizontal reinforcement of No 9 wire and treat as a cantilevered wall for design for out of plane loads. Add rebar in the cavity if you have cross sectional tension.
First: determine if the local building code has adopted the IEBC (International Existing Building Code) by ICC. If so, look at those rules.
Second: if the IEBC is not law, then you should use chapter 34 or 35, I can't remember which of the IBC (Labeled existing buidlings).
Third: don't worry...
Flexible for the most part. Smaller square'er diaphragms are often fairly rigid. Word of caution when considering un-equal stiffness vertical elements. Torsional re-distribution will occur.
I would put some crack control reinforcement - say #3's at 12 EW. There isn't really any load on the thing of consequence. You do not need it to survive a car impact so that isn't a real load. You only want to do one layer becuase you don't want rust staining, but you still need to control...
A few rules I've learned in 10 years looking at drawings:
1. Take a minute to print something out, look at it just like your client looks at it. You often see font/presentation things here.
2. Look not just at what is there but what isn't there. Mistakes often happen by information that is...
HgTX - not a welding expert - but it goes to the amperage used to make a E70xx liquify. You are more likely to burn through light gauge metal than thicker structural metal therefore use the lighter electrode.
I have (2) TI 36X's and an 85. One of the 36x's is almost 20 years old and is still a work horse for me. Its been in mud, in rain, stepped on, rolled over, sat on (and we're talking some weight here boys & girls) and it keeps on calculating. I killed a 35 a few years ago by spilling soda on...
If gypsum can be used to resist lateral loads, to me it can be used to brace a stud for compression and bending. I don't usually use the stud compositely with the sheathing but I understand there are several research reports that indicate this is an acceptable practice.
I say yes. If they wanted to exclude buildings with parapets they would have done so in 6.4 where they tell you the buildings where you cannot use the simplified procedure.
We don't typically add reinforcement, but maybe we should. I've seen some cracks develop down there, so that would be the reason to reinforce - crack control.
First, I'm not a lawyer only an Engineer.
This seems to be a simple case of intellectual property. If you are representing the existing structure in your drawings as "existing" then what you are doing is both ethical and reasonable. Could you field verify the conditions you are showing?
It is...
You might look to make sure the machine is working properly. This happens quite a bit in hotels with the big washing machines and long period 10 story buildings.
I think JAE has it right, and it goes to one of my pet peeves of the code: it is written for the average 8 story building. Engineers who work on smaller structures get very little funding support.
To your specific problem - you can't use a tube because there are no pre-approved joints. I...
Okay, your situation sounds more a push wall than a loading dock. I had a push wall to design once, it was on a trash transfer station where front end loaders would push trash up against a short wall to collect it in the bucket.
in that case it was designed for 10,000 lbs 30 inches above grade...
Design it to retain the soil, and don't worry about the impact. There will be backfill behind the wall that will absorb the force. You can dowel it into the slab of the loading dock. If there was a previous problem with this wall cracking and crumbling the problem is probably in the fact the...
The blockout should be 3-4 inches on all sides larger than your baseplate, but make sure the baseplate (rectangular) fits in the blockout (diamond).
Filler material is usually 1/4" or 1/2" compressible filler. to separate the two pieces of concrete.
So let me get this straight - you are putting the plate so that if you drew a section looking down the beam you would see the width and depth of the plate, not a skinny 3/8"?
If that is true, and your welds are good and not required to transfer any stress from the plate to the beam, then the...
Because most engineers have found that a W10 is the smallest bending member they use. If you cope out an inch of the top of the beam to make the connection like a purlin to girder connection, then you don't have very much room to fit the 2 bolt connection into. Besides, for bending the W10x12...
