I am currently designing a "masonry guardwall". The wall is 5'-00" tall and sits on top of a stone retaining wall. The thickness of the masonry wall is 16" and the reinforcement will be extended from masonry wall to stone wall and maintain at least a development length. The stone retaining...
I am interested in knowling why do you want to use a constant thickness plate for 20m span. I would suggest to use beams with corrugated metal deck.
If steel plate is your final selection, you can read "Plate and Shell" by Timoshenko. This is a classical text book and solves everything by...
Hi:
I remember there is a maximum length for concrete slab without pour strips or expansion joints. Can anyone tell me what is the length and which code section?
If I remember right, this length limitation is different for pour strips and expansion joints. The requirements are also different...
Thanks to lkjh345. That is a positive approach for challenge questions. That is exactly the code language I am looking for. What I will do now is to write a letter to ICC to request an explaination for my case.
Excellent. Thanks again lkjh345.
Thanks, mfrad.
That is the support I am looking for. That is exactly the approach I am going to.
The challenge is the computer racks have to go to some exact locations. According to my analysis, few beams under these racks are overstressed from 2% to 20%. I can live with a 5% or less...
By the way, the 200 PSF of equipment does not apply to the entire room. These computer servers are spread out in the rooms. It is similar to filing cabinet case but lighter.
Based on my analysis, if I can limit the live load to 20 PSF rather than code required 50 PSF, these beams will not be...
Thank you all.
I guess the bottom line is "Limiting occupancy" is not a solution for this case.
Does anyone know any code saying "Limiting occupancy approach is absolutely prohibited"?
I understanding that structurally this approach is not a good idea. But politically, I need to make this...
Thank you for all comments.
The equipment are computer servers with an average of 200 PSF. These rooms will be highly secured and limited personnel. We feel comfortable to limit the live loads for our personal opinion. However, we are looking for a code support so we can stand in front of...
I am currently working on an existing steel building. The composite floor was originally designed for 50 PSF of live load. The building owner now wants to add some heavy equipment to the floors. Based on my analysis, the floor beams need to be strengthened. However, the floor below belongs...
Hi all:
Based on my experience, MS Word files are getting huge while the photos are directly copied and pasted into the Word files. The way to reduce the size of the Word files with photos is as follow:
1. open the photos with Photo Editor or equivelent.
2. Select the photo and copy it.
3...
Hi: all, I hope everyone had a great weekend because I did.
In this weekend, I summaried the ideas from all of you and came out with a great system which doesn't need any frame or heavy foundation. The idea is as following:
We are going to unscrew the inner piston from the outer shell of a ram...
Thanks Ron. As I mentioned before, my system has four legs spreaded at four corners of a square shape. When the load is applied, the two legs in the diagonal direction will be in tension/compression at the same time while other two legs have the opposite reation. In this case, my mat...
Hi: Ingenuity, Thanks for your advise. After talking to our shop manager, we may want to do a mat foundation instead of mini pile as you mentioned. The reason for that is we do not have the right equipment to drill a 10 feet deep hole here and the soil condition is unknown, either. Based on...
