SRE, that makes a lot of sense. Thank you for sharing. I'm more of a steel design man myself, and this is actually the first transformer foundation I have ever seen/worked on. Your insight it a good reminder to trust in my coworkers judgment. I am eager to go down to the site soon to become more...
Agreed, it's silly to design freestanding. But I don't write the contracts...just making sure it doesn't fall down :)
KootK - thanks for the sketch and your input. Very helpful
Oh, I understand. I agree with you if I were designing the wall considering it as a beam between the two other walls. However, I am designing it to be sufficient freestanding in case the owner would like to remove the other walls in the future. I should have clarified that when you asked about...
Jike - That's exactly what I have started to do. Thanks for confirming my thought process. I plan to model it as well.
KootK - I hadn't thought of that. However as windload is governing, I would still need a lot of vertical reinforcement so I'm not sure if that would help. I could be...
Thanks for the replies. There is about 10 feet on either side before hitting the firewalls that run perpendicular. I was going to show in the calc that additional steel provided along the penetration was sufficient to withstand the bending moment of the wall above the penetration. Just wondering...
Hello,
I am working on a 16in thick CIP concrete firewall for a transformer and need to account for a roughly 10' wide by 2' tall penetration about halfway up the 40' wall. Obviously I am concerned with losing 10' of vertical reinforcement and I need to make a force pathway to either side of...
