Thanks but that contradicts AISC DG 11

Thanks, but we know, based on DG 11, that reinforcement that is not properly attached to the floor framing, such as through welding or jacking of posts, is largely ineffective when it comes to vibration mitigation. I am familiar with walking excitation and sensitive equipment. Isolation is not...

Yes, and to engage them so that the reinforcing is compatible with the model. ...Yes, agreed. Which is what I've alluded to in my original post.

Yes, agreed. Although Im most concerned with the beams that are on the right-hand side, parallel to the deck.

It's for walking excitation

Thanks, i mustve missed that portion. I know it discusses the columns. We've discussed it with the specialty engineer. They wanted the beams tight to the deck with no special requirements. They were not familiar with jacking the posts, which made me question their direction.

I've been tasked with creating design drawings from a vibration mitigation study performed by a specialty engineer on a composite framed steel floor with slab on metal deck for sensitive equipment. The specialty engineer used finite element modelling to determine the repairs which consist of...

Deker, thanks for your insight, however, you have assumed we are a structural only firm. Alt0, this is what im looking for. Thanks!

thanks im not interested in modifying state titles. for the california pe's, how do you communicate that you are focused on designing structures on your resumes.

thank you for your insight. however, i am not interested in your response. for the rest, if someone can help me indicate that my Civil Professional Engineer has experience in designing structures in California and not roadways at the top of a team resume, i would be grateful.

yes, i understand that portion. My question is for California PE's that practice structural discipline-type work, how do you list yourself on company resumes. For those not aware, califormia PE's can design structures except schools and hospitals. This is in contrast to Illinois, where ONLY an...

Can you use the term "structural" but not "structural engineer" in your title on company resumes? Would it be Mr. Boiler106, PE (structural)?

Thanks Josh. I assumed that it's jacked up to some percentage of the tributary dead load.

i have a post to place under a beam to mitigate vibration issues supporting sensitive equipment. I understand from AISC DG11 that this column will need to be jacked into place Does anyone have experience with doing this, either in modelling or construction? I'm trying to decide how much...

for the purpose of this post, im looking at 5 1/4" total slab thickness with 2 inch composite metal deck spanning 10ft.

phamENG, this is the route i think i would take, too. i was wondering how you might dowel and connect to a headed stud plate without interferences and could only come up with a bolted seat angle and field-bent dowels. what spurred this thought is that i recall reading about deck failures where...

im glad we're on the same page. i see this detail on the "big name" drawings in several projects.

we rarely get this condition, but i frequently see on other's drawings the slab on metal deck placed over load bearing walls with no positive connection to the wall prior to placing the slab. the attachment is sometimes made with a dowel from the masonry wall to the slab, otherwise, the deck is...

Does anyone have a rule of thumb for clearance required between a wall and beam flange tip for a worker to reach down and put a spud wrench on the back of a bolt? I'm thinking 6 inches minimum.

yes, lots of information. Unfortunate abbreviation.
