Hi all
I have a question regarding fatigue assessment for a steel structure.
I am looking at the design of crane girder to column connections. The connections are subject to fatigue check to BS 7608. I am approaching assessment using a stress spectrum defined by the building owners, using...
Hello all
I would welcome your view on the connection detail shown on the attached sketch. This thread was prompted by a discussion I had with a colleague regarding how this connection would behave.
The building is a 3 span portal framed building. The building has 5 number overhead cranes...
Is anyone aware of any resources which give design data for crane girders - information such as lift capacity, wheel centres, crab weight, bridge weight, and hook approach etc.
I'm working in the UK, so would prefer SI units if possible !!
I've been asked to look at a project where a number of floor slabs within a property have heaved. On excavation of trial pits, it appears that the floor slabs are founded on a slag fill.
I am aware from limited research that these fills can be expansive, and my gut feeling is that this is the...
I don't know if anyone out there is able to help.
I'm sitting some professional examinations here in the UK shortly, and have got hold of some typical past exam papers to attempt as part of my preparation.
I have noted in some of these papers that if the ground conditions comprise clays etc...
Hello all
A quick poll to gauge oppinion :-
A pair of parallel simply supported beams carrying the inner and outer leaf of masonry construction in a domestic 'knock-through'. Inner beam carries one storey of masonry, roof of main property, and first floor joists. Outer beam carries mass of...
I am reviewing a site investigation report for a development.
The ground conditions at the site - firm boulder clay underlain by sandstone, mudstone, and inter-bedded coal seams. The coal seams will be investigated using rotary drilling to check rock head cover and presence of workings.
The...
Hello all.
I'm looking at the design of a footbridge. The form of the bridge is a steel through girder vierendeel truss.
I have been looking in BS 5400 for an indication of deflection limits under dead + imposed loads. There do not appear to be any such limits in BS 5400, but there is a...
I have been asked to design some 'artwork' which is to be erected in a local town.
The artwork takes the form of three polished stainless steel conical tubes which are 600mm diameter at the base, 100mm diameter at the top. The top of these 'spikes' are to be 15m above ground level. The base...
