Are there any good reference works out there on the design and detailing of spiral vortex drop shafts? From my searches so far there appears to be some work on numerical analysis but very little on how to determine the shape of the concrete vortex guide walls or guidance on calculating flow...
I have been looking for information on the sizing of welds. While I can design welds to carry the required stresses, is there any guidance available on the practical minimum/maximum sizes of weld?
In particular, is a 3mm Fillet Weld acceptable for structural applications or is 6mmFW the...
Does anyone have any references on direct comparisons between steelwork designs to BS449 and BS5950? We have a client who is insisting that we re-design our structure to 5950 when we have a perfectly good design to 449. We are looking to demonstrate by literature review that the two codes give...
Does anyone out there have design information (tables or otherwise) detailing preferred sleeper centres for varying rail weights and the recommended wheel loads that these arrangements can carry?
Also, does anyone know of any information on the theory behind rail & sleeper spacings as most info...
Dear All,
I am looking to create a compound beam by battenning together two 'I' section beams. The usual detail is to provide a number of steel plates which are welded across the top and bottom flanges of the beams in order to batten them together.
My question is; Can I use plates which just...
I am looking at the use of 30lb/yd light rail to construct a temporary train track (610mm gauge)in a tunnel we are constructing.
The site team wish to run locomotives and muck wagons with 3.5 tonne axle loads on the rails with fabricated steel sleepers located at 1.0m centre to centre.
My...
I have been trawling the web in search of a suitable beam element analysis software package, allbeit with limited success. I have come across the usual suspects such as STAAD, ANSYS etc. These are marketed as all-seeing all-doing suites with a price tag to match.
I am looking for a beam...
Dear all,
I have a cast concrete section against which I am casting fresh concrete. I wish to form a shear connection between the two using steel pins drilled and grouted into the cast section and acting in shear across the joint
Is the shear capacity of the joint :
a) equal to the shear...
I wish to tap an M24 thread through a 12mm thick piece of steel. This piece of steel is then fitted tight against a concrete surface.
An M24 bolt is then screwed into the hole and stops when it meets the concrete so I only have the end of the bolt being held by the thread.
Is there a method...
We have excavated a 5m deep hole in slightly overconsolidated clay in order to construct a water retaining buried structure. We have sub-let the design of the structure and our designer is specifying that we import selected granular material for backfilling to the structure.
We have identified...
I am designing a large thrust frame for launching a tunnelling machine. I have a plate girder (600mm wide by 1960mm deep) standing on end as a vertical beam. Framing horizontally into this girder is an 838 x 292 UB with web horizontal.
At this connection I have notched the top flange of the...
I have 2no 60mm diameter solid steel bars which I am attaching, one to each end, to a muck skip to act as trunnions. In order to attach these trunnion bars to the skip I am considering using a welded connection. My problem is finding guidance on the welding of such steels.
The steel is...
Having read some papers on the design of deep beams (span/depth ratio < 2.0), the design guidance given is that the beams act as strut/tie structures. A compressive strut is formed from the load on the top of the beam to the supports at each end, and there is a tension zone running along the...

Virtually all SI reports we receive, submitted as a part of a tender package, are presented on paper and often in numerous bound folders. This includes borehole logs, lab test data, contamination testing etc.<br>

We are currently considering purchasing software which will be able to read...
