tables in EN The code drafters will have to rationalise this at some stage but from a designer's viewpoint. EN will take precedence. Structural use of steelwork in buildings: Code of practice for design: rolled and welded . specification defined in BS EN and the individual component. Both bolt codes allow in their clause a variation on the k-‐factor. Vk ≤ 0,10 where EN clause Tightening of preloaded bolts. General.
On Design Build we are very far down the food chain and any query produces shrugs. I feel this aspect strongly as it adds uncertainty and risk and probably cost to the work, that should not be necessary. I have a strong suspicion that the H S File exists somewhere, but inertia and ignorance is denying the designers and contractors sight of the information.
This is an area where a few well publicised prosecutions could provide significant safety benefits. Robin de Jongh. As a practicing structural engineer and former learning professional, I would commend the distribution of the SCOSS Alert Structural stabilityintegrity of steel frame buildings in their temporary and permanent condition but question the efficacy of including such a long list of learning points.
Multiple learning points can serve to water down and ultimately lose the impact of the message. The clear outcome of the alert could have been a warning that site welding or re work is inherently dangerous, and needs to be carefully procured, managed, and checked. The new CE marking law requiring steel fabricators to be at least Execution Class 2 for any site welding should help us out here, but is not widely implemented if at all and I would suggest a note in the next newsletter advising all structural engineers and project managers to insist on seeing evidence of EC2 certification from any steelworker engaged to do site fabrication or modification of steelwork.
Leaving aside that little note of caution, I love reading the reports and newsletter, and thank you and the team for all the hard work Correspondent. I read item 6.
D Modelling Newsletter No 4. I recognised this issue it is something I have been debating and discussing with our own BIM manager for a while.
It is my view that engineers have become too remote from the current 3. D software, as it is far more complex than the 2. D cad in which we were able to dabble. It means that there is less engineering input to 3. D models than there would have been with traditional drawings. In effect the model is owned by someone skilled in operating the software rather than skilled in engineering.
Despite having been involved with 3. D drafting for the best part of 1. I now find it very difficult to check 3. D model output. I usually need to look at 2.
D drawings, which are vulnerable to error if they are sliced through the model at the wrong point, because they potentially dont show features above or below the model slice. Covered electrodes for manual metal arc welding of non-alloy and fine grain steels.

Current, Work in hand Publi shed: December the choices below: This includes structures and manufactured components produced from Quality requirements for hot rolled, structural steels; cold-formed components and sheeting; hot finished and cold fusion welding of metallic formed structural hollow sections, as well as austenitic-ferritic and ferritic stainless steel materials Criteria for the products. BS EN starts by defining constituent products, such as steels, welding consumables and mechanical fasteners.
It also looks at the preparation, welding, testing and erection of structural systems. Other topics include inspection and correction to ensure maximum levels of quality control. Who should download it?
