Thanks for both your responses. So if, at the center of the roof, there is a vent of some kind, and neglecting the thermal aspects, is there a vertical pressure from the fluid itself, or just from any trapped air being "squished" (which won't happen because of the vent)?
I'm just trying to...
Hi,
I have a client that is requesting to fill a 2" in 12" self-supported cone roof up to the very top (apex) of the roof with liquid. I know this raises alarms in regards to venting, etc...
What my question is - how does the liquid apply pressure on the underside of the roof? I would...
Hello,
API 650, 11th Edition, Section E.6.2.1.2 has equations for seismic anchorage. However, Section 5.12 in combination with Table 5-21 has equations for seismic anchorage as well.
The question is, how have you approached the two conflicting equations? Do you look at both and use the most...
I just had to redesign a 304 SS tank with a similar bottom (but much smaller diameter). They had used one central column with 6 radial beams spanning from the center column to the outside legs. Because these beams are taking the full weight of the product, they are going to be large. For my...
API 650, 10th Edition, Addendum 4, Section E.5.1.1 defines the response modification factors to be used with the standard. If you compare these values for the impulsive component (3.5 for self anchored and 4 for mechanically anchored) to ASCE 7-05, Table 15.4-2 for flat-bottom ground-supported...
You could be conservative, and design the connection and members for both cases, fully released and fully fixed. This will give you different moments in different areas of the beams and columns which you can design for the worst case.
Whenever I have a pinned support, I use the following support:
FIXED BUT KMX 1 KMY 1 KMZ 1
This is telling STAAD that a VERY small moment can be acheived at the supports. In reality, this is true. You could apply a small moment to a "pinned" support, and have no rotation.
This prevents any...
If you are looking for a blank cell in column AU, isn't column AU the 47th column? Maybe that's the problem.
Also, if you have text in au3244, then it wouldn't hide per your macro, correct?
Actually,
The code you show:
Rows("3:65203").EntireRow.Hidden = True
should be:
Rows("3").EntireRow.Hidden = True
The problem with this would be if you hide the row that your cell is in, then you have to unhide the row to input a different number.
Also, the "" doesn't work in the macro...
Try this macro:
Sub auto_open()
' Run the macro DidCellsChange any time a entry is made in a
' cell in Sheet1.
ThisWorkbook.Worksheets("Sheet1").OnEntry = "DidCellsChange"
End Sub
Sub DidCellsChange()
Dim KeyCells As String
' Define which cells should trigger the...
The following is an excerpt from a spec concerning grout on a basin slab:
A. Grout:
1. Proportions of Grouting Mixture:
a. One part portland cement and 4 1/2 parts sand, by weight.
b. Water Content:
1) Sufficient, to allow workability for spreading grout with...
