I have been previously rejected by a plan reviewer for having slab steel bend to bottom of footer. They ambiguously stated that the detail violates ACI but i cannot seem to find this restriction. In that note, how would this recessed shower detail be corrected?

I always thought you would be able to see tension rods from the ends of the beam if it is prestressed, but i was told by a contractor that is not always the case. There is an overhanging T-beam that we want to cut but someone pointed out it may be prestressed and not a good idea. I suppose the...

well i suppose here is the main issue. There is an interior frame wall that is supposed to only have drywall (so no structural sheathing). There IS a load being applied on the exterior. I'm trying to figure out a quick and dirty analysis that would make this frame work for an applied load. I say...

Hello Can someone tell me if my simple check on this shear wall is reasonable? I am checking for tie down of shear wall to the foundation. (of course I also check the shear component) Also, if this check works out, is it reasonable to assume that the wall diaphragm isn't taking half the shear...

THANKS

is there a book or reference material someone can suggest? i bought an ICC book by Terry Malone but it seems the material is too advanced. the problem are very complex

it is single story light gauge metal. I assumed rigid.

hello everyone I am having trouble with this type of analysis for a small structure (attached diagram) I am going off a example i found in a book. When i get the value of Vmid, i am comparing it to the lateral capacity of the sheathing. (for the exterior) What do i do with the interior? i am...

hello everyone can you guys please provide me with reference material for the installation, design, etc. of these topics: - Boilers/ pressure vessel systems - Condensate piping - Low temperature refrigeration - Piping for lift stations - Piping and installation of gasoline tanks - Gas...

Hello All I am using Accuload for cooling load calculations for a home. What i am having an issue is how would i accurately simulate the walls that are adjacent to an unconditioned garage? It is obviously not exterior so the sun isn't beating down on them, but it is abutting a warmer area. I...

that's not the issue. fixed bases also resulted in the same problem

here is the sketch @XR250 thanks, that's kinda the confirmation i needed. Just wasn't sure how to simulate this. (i eventually restrained both top plates and was debating on just doing one)

It's been so long i've worked on structural, i can't believe i'm in need of assistance for something so (seemingly) basic I am analyzing a simple 2D frame (two walls, two rafters, one joist, two interior braces). Pinned connections at base. When i run the analysis, i obtain rational stresses...

that's how engineering works. products need to be qualified. why answer a question with another question when you're ignorant with the regards to the topic at hand?

NCEES is ridiculous with their testing strategy they WILL include questions that will be on a previous edition but lead you to the INCORRECT answer. I suppose they make money off of making people buy the current edition of books (not that being able to use an old one isn't an indication that...
