I know generally punching shear isn't a problem at the shear wall, but it's at a point we are considering afding SSR to shear walls.
Any help would be appreciated!
Edit: "How" can I check punching shear at the shear walls?
"How" is missing in the title
Had an electrician come install a new outlet behind where the tv will be hung. When he opened the drywall he saw the shear wall (5/8” plywood) and told me that I don’t have to worry about hitting a stud when I mount the tv, that the shear wall will hold it fine. Is this true? I know where one stud is and I think it will work to get one side of the mount in it and still be centered with the wall.
Hi everyone, I am a structural intern and need some help on an exercise.
I am working on a small CMU shear wall for a garage and I’m not sure how to check if #5 vertical bars (going into the foundation) at the ends of my shear wall are enough.
Wall dims: 9’ long x 20’ high (2-story) Grouted @ 24” OC
Have all my wind loads and moment calculated, just not sure how to hand-verify those bars.
Thank you!
Hi All,
We recently learned that our plans to install a sliding door may be too rich for our blood. There is a shear wall right where we want to install the sliding door. Before we bring a SE out and waste anyone's time, we were wondering if anyone can give us a ballpark cost or even viability to complete our dream, sniff.
Is it possible to remove the two existing windows and put the shear wall(s) in their place, then install the sliding door where the old shear wall was?
We understand that once we get the SE plans, we will then get ~3 quotes, etc. We are just trying to decide if it is worth anyone's time.
Edit to try to add the pic here:
Thx
Hey all - looking for material anyone has on designing cold formed studs with wood sheathing shear walls. I have experience designing wood shear walls for all wood projects, and was wondering what the differences are when you're using cold-formed studs (obviously, doing this for the first time due to wood shortage. Will this please end soon).
Obviously the biggest difference is you're limited to screws only and can't use nails, but I'm wondering what, if any, strength implications it has. I was planning on using the NWS manual for shear strength values same as wood, and just making sure the screws are close to the nails being specified in the design manual.
I am working on a residential project. It is a 3-story home, wood construction.
There are very few exterior walls that can be used as shear walls because of the following:
- There are windows almost everywhere.
- Not all exterior walls are aligned vertically (some overhanging segments that don't track down to foundation).
My question: What is the typical expensive alternate solution to a typical shear wall to track down lateral loads? I am struggling to find a creative solution for the architect besides "remove these 3 windows".
Some background for the project...
Footprint is ~55'x70'
Flr-Ceiling height is 9'-0".
Gable roof.
Edit:
Thank you everyone for your help in the comments.
Even with all the additional support, I didn't feel comfortable doing the design for the project and passed it along to another engineering firm.
I have a close relationship with the client, and they may let me see the final structural drawings done by the other group. If so I will be sure to let you know what the final solution was for the lateral track down issue.
Hi everyone,
Im currently designing a structural retrofit for an old concrete building (1957). After several tries with different structural systems it seems that using steel plate shear walls would be the best option. Im trying to avoid to destroy parts of the actual frames that are built, but of course this system needs boundary elements attached to the existing structure, so my question is: Do I have to attach the new boundary beams of the SPSW system to the old ones or can I avoid this as long as I consider it like that in my models? Is there any code restriction that force me to attach the upper boundary beam of a level to lower boundary beam of the next level?
I am completing a project on the effect of wall shear stress on blood vessel walls but am unable to find an analytical method for finding the max or time averaged WSS value. Do I need to know my pressure gradient first? My parameters are currently at: -pipe diameter=6mm -viscosity=0.0035 -density=1045 -velocity=0.353678
Hey guys, i am an architecture student and i am working on an old building that was built more than 100 years ago, the structure of the building is shear walls made of stones, and i am wondering if i can make big voids in the shear walls in order to make sliding glass doors in all the building and add steel beam and two columns around the void for load distribution... , in other words i have to make the spaces more modern and transparent...yes or no please ? If yes how can i join the steel columns in slabs...if no any suggestions on how to make that possible please ? And thanks a lot 🙏🏻
I am new to cfd and modelling a nonslip 6mm pipe flow on starccm. I have managed to get a velocity vector scene but am struggling to figure out the wall shear stress of it. How do I go about finding a max wall shear stress value?
Is there any good data on how much shear force capacity interior walls with metal studs have? Metal frames are so popular now, which one would imagine is causing a shift in the way people decorate.
This would be valuable information for people who have hanging TVs, book shelves, mirrors, pull up bars, whatever
I tired using a line probe to get a XY plot for my velocity (vs Y point) and Wall Shear Stress (WSS) , but I cannot see the WSS plot. The velocity plot came out okay, I was wondering how to convert a velocity graph to a WSS graph. (maybe on Excel or some other way). i Know the formula to convert it is (SS = viscosity*du/dy) but I'm unsure how to type this into excel. If anyone could help I'd really appreciate it.
I can’t find studs in the wall in my garage that’s attached to my house. My friend who is a contractor said that it’s likely a shear wall. Does anyone know if tonal can be installed on a shear wall?
Chemical Engineers - your help would be appreciated. I'm trying to work out how to calculate the wall shear rate in a stirred batch reactor. It was easy enough to calculate the overhead impeller Re, but I want to be able to compare the wall shear rate in the reactor to the wall shear rate in a flowing pipe to link laboratory to actual field / plant conditions. Is this possible? Or is it adequate to compare Re number in both scenarios? Any help would be greatly appreciated.
What is the advantage of using concrete walls for a room like a gymnasium instead of steel columns like most of the rest of the building?
In stick-built construction. I'm under the impression that the inset diagonal brace is an older style. However some shear walls just have plywood nailed onto them... but wouldn't that mean that virtually every exterior wall has the characteristics of a shear wall because they generally all have wood sheathing? Or is it a more extensive nailing pattern that makes it a proper shear wall?
I do understand what a shear wall is for and that only certain walls need to be shear walls.
Thanks!
Hello everyone, when I create the scene for the wall shear stress nothing appears. Probably I choose the wrong parts or region. Any help or tutorial to follow in the creation of WWS? Thank you so much in advance!
- Location: Indonesia, jungle area (no code), earthquakes which are not often, are 6.0-6.9
- I am thinking about doing lightweight steel framing
- I want to see if I can skip plywood for the shear walls due to poor quality and untreated wood here, lots of termites too
- I found fiber cement board that is for outdoor, says its "more durable than plywood" but wasnt until now that I got a shear value number. It says "Shearing strength (N) according to EN 520 = 607"
- Does anyone know the number I should be aiming for regarding shear value for a wall?
- I cant determine if this "607" number is sufficient or not
