Hi all,
thanks for the feedback. Apologies for not responding sooner. I am grateful.
the wall was going to be two skin 100mm block with a central 100mm cavity. As dik mentioned, using just masonry wasn't an option, which is why I am introducing the concrete core. This led to the question on...
Hi all,
I need some guidance on how to calculate for the reinforcement steel in retaining wall.
I have 2 block skins, infilled with a concrete core. each of 100mm thick. I was being conservative and ignoring the blocks in the design, just evaluating the concrete core. however this gives me...
Hi all,
I'm looking at a project where there is a simple steel frame structure, made of PFC sections. The frame is to be clad in 3mm thick di-bonded cladding (2 sheets of aluminium enclosing a Polyethylene core). size approximately 5m tall, 7m wide, 1.1 m deep (it is a arch structure which will...
Hi Tony1851,
after taking some guidance from the responses I received, particularly with respect to the deflection limits, I ended up with the following:
limiting the opening to 4.8m. this was more to do with the available clearance above the beam (conflict between roof line and the new...
I was thinking that Acroprops and "strong boys" would be used to support load, while enough of wall is demolished (and piers built) for the new beams. Beams would be installed one at a time. Once ready, the strong boys would be removed one at a time, and the gap packed out in sequence.
The two...
Hi guys,
OK, I must apologies, I hadnt linked the L/688 to the 8mm for my particular span. I was looking within the document for the actual ration L/688. I do appreciate the support (pardoning pun) you guys have provided.
Well the 8mm is certainly something new to me, with my 15mm deflection...
Hi all,
so I have selected a 356x171x57 UB
this supports the full load independently, so doubling up the beams provides alot of redundancy and covers the TIF factor (Things I forgot).
it meets the L/360 requirements for Eurocodes (for beams carrying plaster) so I think the deflection is OK...
Hi all,
I really appreciate the feedback. I'll let you know steel sizes and see if that changes anyone opinion tomorrow.
I saw the sketch linked of small top plates at intervals and beams on out edges. (thanks) imteresting idea. I'll get back to you tomorrow. Cheers
Many thanks!!
I didnt check the basics before I proceeded. The depth/span ration is out and because of my not checking I overlooked an error in my calculations. I have a 20mm deflection which is too much. I originally read the 20mm as 2mm and thought nothing more of it.
I may be able to use a...
Hi There,
thank you for the feedback.
The loads are relatively light as the wall is a first floor wall with only a roof gable and roof loads above. the clear span is 5.5m.
I have been conservative with the loadings and have sized based on a single beam supporting the load.
I'm just not sure...
Hi there,
I'm based in uk and have done some calculations to size beams to replace a load bearing stone wall
Wall thickness is 530mm so approx 500mm stone/mortar wall excluding render.
I have sized 2 off 203x203x 46 uc beams. This only comes to 406mm total width.
I'm not sure whether I...
