Thanks for getting back to me.
Yeah kootk I had FEM in mind to analyse this but was wondering of there was a way to simplify it by hand.I will have a look at the 5t rule tomorrow in the office and see what I end up with. If it is unrealistic then FEM might be my best bet.

Hello All,
I am currently working on a project where the client is looking to construct a mezzanine level within an existing portal frame structure. This shall be a fairly heavily loaded mezzanine as there is plenty of plant to be stored on it.
We have been searching the council archives for...
Hello all,
Some engineers say they are comfortable using 1.0 as a stiffness modifier when analysisng concrete cores of tall buildings under wind loading. Is there any specific guidance on this or is it just what is comfortable. Im working to eurocodes.
My thinking was to look at the analysis...
Thanks for your replies everyone.
CANPRO - very good description that made it all alot clearer to me now, initial sag is only really to find your initial tension.
HOTROD - Yeah I have seen various handrails with rigid top rail throughout, although never had to design on. I can understand why...
CANPRO, sorry for not getting back to original post.
How would there be sag in the horizontal direction, would there not only be sag in the vertical? Or do you mean the sag after the horizontal imposed load has been applied?
I can check the pictures when I am in office tomorrow and try to get better idea of the spacing, it was a colleague who visited site.
Yes that's true, we should have a rethink of the load we are looking to apply, bit of engineering judgement.
The posts for the wire rope is 100x100 SHS's. I...
Please see the attachment, it only looks like vertical spacing is a requirement where there may be children present. The architect may argue that there will be no children present in the gym to get around this regulation.
The 300mm spacing was an estimate as I dont have the project infront of...
It's a barrier around a raised platform (raised 600mm) within a gym environment, there is basically posts with 3 cables running between them so spacing between cables must be about 300mm vertically. They have wrapped these cables in foam to make it look like a boxing ring, although the area will...
Hello, has anyone had to calculate the tensile stress on a cable balustrade which has UDL applied along its length?
Looking from guidance online most calculations seem to be based on an initial sag, which we don't know and for horizontal loads it will probably be 0mm.
We know the tensile...
It was the temporary works side of it that was causing me concern.
Should it be cut in "hit and miss" sections say 1m long, packing below to support and then once this is in place remove the remaining slab.
I think it is badly drawn and it is infact a suspended slab.
I think they are proposing to pack the underside after they have cut it back to reinstate it.
Hello,
I have came across attached detail and was wondering what everyones thoughts were on it.
There is a requirement to add an additional strip beside an existing strip as they are looking to extend upwards thus increasing load. This foundation is currently on party wall between garages...
Yes I have always thought the wall would end up taking restraint off the jamb but this seems backwards as the door/window system is normally designed to be fixed to the superstructure. There is no timber jack between door and window, just a PVC jamb.
I didn't think it could be justified to say...
Hello all first post on forum.
Please see attached for reference. These doors get used everywhere in the UK and I was wondering how they can be justified to work structurally apart from the usual response of "we have used these everywhere".
This situation may arise in timber frame construction...
