I have a request related to the formula - could you please take a quick look in your geotech/foundations text you have on hand, look up the lateral earth pressure due to a strip surcharge load formula, and provide whether it has the pi or H in the denominator? I'll start with what I've found so...
In all of the geotechnical and foundation books I have been able to round up post-1998, this formula (or one without the factor of 2) is given for the stress on a retaining wall due to a surcharge strip load. In books from 1998 and before, the pi in the denominator is replaced by H, the height...
@KevinNZ - I think going with a circular base plate calc based on the flange dimensions is probably the way to go. Thanks.
@dgeesaman - no pressure and WAY down low on the S/N curve, so essentially static.
I'm using a piece of pipe structurally for something that needs to be disassembled. Least expensive way would be just to buy a flange and throw it in, right? The problem is, I cannot find any information regarding the global moment strength of a flange/flange connection. I feel that the...
The short answer is no - for many reasons. A few of them:
- How would you define g, the transverse center-to-center between fastener gage lines? Welds do not have gage lines.
- How would you define s, the longitudinal center-to-center spacing of any two consecutive bolt holes? Welds do not...
Oof - I think this one went WAY off the rails on the sphere. The sphere is strictly for sizing of openings (at least in the US) and the designer is not intended to try and ram it through. The cable must take 50 plf or a 200 lb point load laterally. Interestingly, IBC Section 1607 does not...
SRSS is definitely the way to go, but your question raises other questions:
- Are you trying to design a connection that will let the two buildings move independently of each other?
- Will you tie them together and prevent relative motion in just one direction, NS or EW?
- Will you tie them...

It was pretty tough. I'm not sure I did very well. Not having tabbed books next to you is a definite hindrance. I spent too much time going through the PDFs...

Yes, I entered the AISC contest and won one! I'm featured in the February issue of Modern Steel Construction...
ASCE 59 gives the limit state load combination of 1.0DL + 1.0LL + 1.0BL as the only combination to be used. It then says we are to adjust live loads and dead loads based on whether they help resist the blast load or add to it. That I understand. What I am trying to nail down is whether this...
Picked up a 48SX and 2 years later upgraded to the GX in college. Now use a 48G (only accesses 32k of RAM instead of 128k - much faster).
It's on my desk and used often for two reasons:
1. It is great to bang out some quick numbers to get in the ballpark before getting serious on the...
Not a bunch. It's more for construction ease than anything else. The anchors near where the beams intersect the channel will take 99% of the load.
-5^2 = -25 ;-)
We have a case where we are anchoring the back of a channel to a concrete wall, then attaching several steel members perpendicular to the channel.
Is there a maximum spacing between anchors that we should use? I don't like the idea of a long span of the channel not stitched to the wall. For...
