I have a thin walled circular tank buried underground. There is no positive connection between the lid and the top of the tank, so its essentially open ended. I have worked out the compressive stress in the wall. Can anyone give me an expression for the bucking capacity of the wall? Much of the...
I have a question about a specific plastic analysis case, some of you guys may be of help. I have a beam fixed at one end and a cantilever on the other. Most common continuous systems will require 3 plastic hinges and the collapse mechanism will be independent of the load on the adjacent spans...
This is not a stricly Engineering problem but someone may offer some insight.
For under floor heating on a concrete ground supported slab I require 110mm of insulation to satisfy the U-value requirement.(Sourse- insulation manufacturer backed up by my own calcs)
Hense my ground floor build up...
Hi all,
I have recieved plate bearing tests on 'made ground' and the results have been issued as a modulus of subgrade reaction and CBR percentage. From these results can anyone indicte to me how I can estimate Bearing capacity for a design of a raft slab over? Thanks

I am designing my first moderately high building (10 storys). In other buildings to date I have used shear wall construction before but as axial compression due to vertical loads have dominated, lateral/ wind loads have not been critical.
With this building I intend to provide stability using...
I am currently competing a report on a roofed thin walled steel tank, whose walls have structurally failed. The designers calculations only designed for the load condition whereby the tank was full, ie hydrostatic presssure. The tank was being emptied for servicing however, through a scour valve...
