    Steel Knee Brace to stud wall

    Thanks for the replies, good points all. Couple things, this is new construction, so no issues detailing it how I want. Yes, cantilevered isn't an option, and that would be ideal. Stud/column has been sized for bending, and I believe I have a good handle on other load path details. I did not...

    Steel Knee Brace to stud wall

    Hello, I have a situation with a steel knee brace coming into a wood stud wall. This is a residential balcony, I have no input on balcony design. Only being asked to size studs and advise on connections. My question is on the connection of the knee brace to the wall. Ideally I'd like to...

    Trench Footing

    Hey. I have a PEMB foundation design, and the client want to use "trench" footings. Basically, they want mass concrete for the foundation walls and footings, no piers. The client is a general contractor and it's their PEMB building, so I'm not going to argue with them. I'm curious how anyone...

    Crack in block basement wall

    Thanks guys/gals. Ya I just used one of those cards with different line widths, but agree, I'll need a more precise method as you two described. My concern with the steel option is potential future buyers would be put off by seeing that, the fibers are more discreet. But hopefully I don't have...

    Crack in block basement wall

    Thanks for the replies, relaxed my mind a bit on this. I'll monitor it for now, and fix the grade under the deck. Hopefully if I keep the water away, i won't see any more movement in the wall. Should be fun!

    Crack in block basement wall

    yes, I do live north, in Michigan. Freeze/thaw was my other thought, being that the crack appeared in the spring...The wall has been through many cycles though, so I would think this crack was likely pre-existing and just covered by paint if that were the case? Do you think a fix is necessary...

    Crack in block basement wall

    Hello. I have a pretty typical horizontal crack in the mortar of a cmu basement wall. Unfortunately, this is my own basement. I am a structural engineer, but don't have much experience in this area, and was hoping I could ask a few questions. Some info: House was built in 1955. Low basement...

    PE exam steel beam Cb value

    Thanks for the responses. Feel much better knowing they review these questions after the fact, and people can write in to tell them of any issues. If anyone feels like responding to another question: in general is the NCEES provided practice exam a pretty good indicator of the test difficulty...

    PE exam steel beam Cb value

    Thanks for the reply. I would hope it will be more clear on the actual exam. Just concerning because this is the NCEES practice exam, which is supposed to be based on actual exam questions. The fact that they give you a load diagram would make me think they expect you to determine the Cb...

    PE exam steel beam Cb value

    This should be simple, but there seems to be different ways to go about it. On the latest practice exam there is a question asking you the allowable capacity of a steel beam, braced at midspan, with a point load. The solution provided determines the LTB capacity of the beam to get the answer...
