ironmon,
havesealwilltravel's last sentence sums it up "Stamping drawings prepared by people who are not under your supervision at the time of the drawings creation is unethical and degrading to the engineering profession.".
As per comment made by rapt, you can sort of "act dumb" and keep on...
thaidavid40, You are right, the client has expressed preference for swing doors over sliding doors.
I feel that with sliding doors, the design of iron mongery would be simpler.
Haynewp, along with leaf, we have to design for door frame, hinges and bolts.
We get the forces acting on these items...
I found SAFI , a canadian software to be a good candidate for small to medium scale firms.
The user manual is compact and written in a nice engaging style.
Hello MillR,
I would suggest that any software that you are going to use should have two characteristics for effective post analysis
1)Selective reporting about the design, selectiveness being defined by the user and not a drop down list supplied by the package
2)Some sort of easy scripting...
I've come across designs of doors with filled with concrete, but they were designed for about 5 atm (~50 t /sqm).
This case though is far more than 5 atm.
1gibsons suggestion though meant in jest, does indicate some way forward. May be a damage absorbing replaceable cladding is the way forward...
Hi IRStuff,
I've done some Web Search and come across Sadvosky's equation.It is a three term eqation with dominating term of 7.0*TNT weight in kg/(distance in metres)^3 = 7*50/.5^3 = 2800 atm
This is almost impossible to design to. I'm pondering over the matter, as to should I inform the...
Hi All,
We have a request from client to design a sliding door system to resist explosion from 50kg of TNT at distance of 0.50 m.
Now, I'm familiar with designing for blast resistant doors in petrochemical facilities, but this is something entirely different.
Are there any design guidelines...
The way I see the basics of this solution can be explained by the following table:
Storey Load Capacity Shoring Remarks
10 100 0 100 Concrete is fluid no strength Use 100% support
9 200 100 100 66% of strength developed use 100%...
Hi Heck83,
For smaller areas, we take the so-called "lesser time average".Let me explain.
The wind velocity to be taken is a function of height( well understood by all) and time t(not so well understood.
Let me illustrate with an example.
Given :- Wind velocity Vbasic of 35 m/s at 10m above...
Hi all,
Thanks for so many comments, siggestions and observations.
I specifically want to know about the following.
With the 1 girth weld ,2 staggered longitudnal weld, will there be any potential issue ?
Like uneven contact along the girth resulting in weld of bad quality.
The Cone will support...
Hi,
I have a query regarding fabrication of Cone transition piece.
the cone transitions from 2000 mm to 1200 mm.the cone height is 3600 mm
As per contract, only a single longitudnal seam is allowed.
The fabricator cant roll such a long section, so he is proposing to roll the section in two to...
Hi Retrograde,
The formation of plug cannot be ruled out.
Such "plugs" can form even in diameters as large as 20m.Iam thinking of cement silos and design of silo walls.

Hi SlideRuleEra,
You are right that if plug is formed at the toe, soil will not enter the pile.
This though is not easy to ascertain(and convince others).We cannot justify as to when and when not a plug gets formed.
So to be on safe side, it is assumed that all of the pile is filled with soil...
Hi SlideRuleEra and Motorcity,
Thank you guys for the suggestions and SlideruleEra for kindly sharing the resources on Pile Design.
The effect of self weight is not negligible, as I have a large dia pile with a lengthy penetration.Let me illustrate my case with numbers.
I have a pile that is...
Hello All,
In the case of open ended, tubular steel, friction piles, should we consider the weight of soil plug, inside the pile, as demand on pile ?
Can it not be argued that the soil has done necessary readjustment to itself,whilst driving and thus the weight of plug has the same status as...
I have to arrive at preliminary estimate for a offshore process platform.
The topmost level will recieve a package of PGC module .
There are two ways to this approach.
First approach, the vendor provides everything, including the structural system.The disadvantage of this
approach is that the...
Hello zdas04,crshears,littleinch,
Thank you all.
With your inputs, I was able to push the disscussion in favor of providing a new three stage PGC.
Fortunately good sense prevailed.
I can now push ahead full steam on designing the structural topsides and jacket and firm up my offshore instllation...
