Hello all!
I have a single story building with bar joists bearing on steel beams. In this particular case I have a 31'-6" span and the loading on that beam is DL=.687 klf, LL=.687 klf, Ult WL uplift=-.721 klf. In order to reduce the size of the roof beam, I've decided to brace the bottom...
I've been asked to provide fees for a renovation of a single story clubhouse. The client would like to provide very large openings in existing load bearing walls at some locations, new door/window penetrations in others. He would also like to remove a portion of the exterior wall to provide a...
The architect has asked me for an alternate design for the standard composite metal deck framing.
I have a floor system consisting of hollow core plank bearing on steel beams. Can the steel beams be considered composite if I size headed studs on them?
Thank you!
The current ASCE 7 references a uniform live load for parking garages of 40 psf. This is reduced from the previous versions which referenced a 50 psf live load. Within the commentary, it appears to also allow for this same 40 psf loading even if the parking garage is utilizing valet parking or...
I went out the a job site and noticed that the concrete on the bottom side of the hollow core plank appeared to look like it was "stretched" or "ripped." I've attached a photograph of one area. Would you consider this finish "typical." It's the first time that I've seen it.
Thank you
I understand the conditions for a partially enclosed building per ASCE 7. It states:
1. the total area of openings in a wall that receives positive external pressure exceeds the sum of the areas of openings in the balance of the building envelope (walls and roof) by more than 10%, and
2. the...
I need some help evaluating this retaining wall. I know that there is "extra" reinforcement shown in the detail, but I was hoping for some input on the detail.
Essentially, the only rebar that doing work is the left vertical bar in the wall and the bottom right horiz and upper left horiz in...
I have a project where the roof trusses need to be constructed with piggy backs due to their height. The roof is also configured so that this piggy back condition occurs at the gable end of the building. Typically, I show the standard MiTek gable end bracing details. However, because the...
I have a warehouse that is 42' tall at the eaves and I'm wondering what I should specify as the minium FF and FL. There will also be racks that are 30' tall. Would this be considered a narrow-aisle, high-bay warehouse that requires a super-flat floor as defined by ACI 302.1?
Is there a...
I have a condition where a 1/4" fillet weld has already been made. Now, a 5/16" fillet weld is required. Is it acceptable to just ad the additional 1/16" of weld?
Thanks!
