Further to the thread below looking at alternative calculation software, I stumbled across another possible contender call Tech Editor.

I haven't tried it but the website blurb sounded promising. Unlike SMath, which is Russia based, this one appears...
I am looking for some pointers to the correct US standards for the design of stairs, access platforms, walkways and handrails.
I have had a look at the OSHA website but I'm finding it difficult to sort through the information, and I'm not even sure I'm in the correct place.
I'm based in the UK...
There is an article in the Guardian Today. It seems like the Engineers are the worlds worst enemy, with concrete being the weapon of choice.
A few quotes:
"concrete is the most widely used substance on Earth"
"third largest carbon dioxide emitter in the world"
"concrete is said to be...
As part of the design of a subsea structure a critical load case to be assessed is the dropped object case. This is critical to ensure the integrity of the equipment contained within the structure.
Impact protection is often provided with roof panels fabricated from flat steel plate. The...
Firstly, this is not a railroad question. I have a site where we fabricate steel structures to support oil and gas developments. These structures can be quite heavy. The site uses a railroad system and purpose designed bogies to move these around.
The bogies consist of 4 x 200mm diameter...
I have a detail (see below) where I have a 250RHS resting on a 150SHS corbel, which is itself attached to a 406CHS.
I am looking at the tubular joint check (RHS brace to CHS chord). I am looking for some guidance into the joint capacity where the incoming brace is eccentric to the chord...
I saw a link to this pop up on my LinkedIn feed this morning. This is called Mola Structural Kit and is a construction toy that is supposed to mimic real structural behavior. There are some videos here.

I am soon to be looking at a project in Australia, which will be designed in the U.K., to US standards and fabricated in Australia. Such is the nature of offshore projects.
We typically use sections and grades available locally. So in the UK this would be sections to BS4 and BS EN 10210. Steel...
I am looking for a copy of this ASCE manual.
http://cedb.asce.org/CEDBsearch/record.jsp?dockey=0042891
I have purchased a copy of its sister publication, the Structural Plastics Selection Manual (MOP 66), but this one is not available on the ASCE library.
I am looking into doing some...
I have a puzzle which must have a reason which I am not seeing.
Consider you have a symmetrical angle subject to an applied moment about one geometric axis. You can calculate the bending stresses (using M/S with S calculated with respect to the geometric axis) for each of the stress points on...
I should maybe have posted this in the Puzzles forum.
I am trying to find a method to approximate the equivalent (effective) density of a pile of chain, randomly placed in a heap. Google came up blank, at least using the search terms I could think of.
My initial thought was determine an...
I thought this might be of some interest.
The main bridge carrying traffic north of Edinburgh has been closed as cracks have been found in the structure. We don't have many of these in Scotland and the Forth Bridges are a bit of an icon. The closure has caused chaos.
They are building a...
In this thread UcfSE is US based and was looking to specify a steel grade in Europe.
thread404-381450
I am now in the reverse situation. I need to specify a material grade for some steel to be fabricated in Houston. At home this would simply be called out as S355J2+N to BS EN 10025. In the...
This is one that occurred in the office and it got me thinking. It is a question about twin fillet welds placed close together. I have looked around online but couldn’t find anything specific.
Please see the attached sketch.
The background here is seafastening equipment to a vessel deck...
I am looking at situation where we have some lengths of Unistrut being used for supporting light loads associated with some subsea controls. In some instances the Unistrut will be biaxially loaded with a UDL (0.13kN/m about minor axis and 0.82kN/m about the major axis) so instead of using their...
Does anyone know if this is still published? I have an 1986 copy and thought I would see if has been updated. However a web search yielded only second hand versions, Amazon has a second had copy in New York for £1,087.91 + £2.80 delivery.
Is there any way to compare V Notch Charpy tests?
The commonly available steel (to BS EN 10025) is tested at 27J at -20 degrees. The design code requires 35J at -5 degrees. Is there an approximation which would allow you to say that a 27J impact at -20 deg would similar to a ??J at -5 deg...
We have been having a discussion about the origin and the method behind the use of a nominal load for designing member lateral restraints. The UK code BS5950 states that restrainst should be designed for a force not less than 1% of the axial load. The old code BS449 states this should 2.5% of...
I am looking at moving a 10 tonne steel frame over a fairly rough concrete surface. The item is on a small quay which is loaded with other equipment. The frame is narrow (about 1m) and long (about 16m). The frame needs to be moved about 100m.
We are restricted in terms of space so cannot get...
