I'm modelling a chamber in STAAD.pro. It is a symmetrical cruciform shape with symmetrical walls with 8 pinned supports in a symmetrical arrangement. I have not applied any horizontal loads to the structure, only vertical loads on the slab (and no self weight on the walls).
I have applied a...
We're designing a piled tank for a sewage treatment works to Eurocode 2. The slab needs to be water retaining so thermal cracking is an important consideration.
Can anyone offer any advice on how to estimate the restraint factor (R) due to the piles?

I'm working on a project where we have lots of sites which require additional 300mm dia. ducting installing (for gas extraction). The ducts are generally elevated 2.1m above ground on metal stands to allow people to walk below to access other parts of the site.
On other projects ('designed' by...
We are working on a drainage investigation, a significant part of which involves calculating the flow capacity of a 100m long culvert beneath a road and some houses to see if it is likely to surcharge.
We want to determine the gradient of the culvert to verify someone else's guesstimate which...
We've been asked to check the adequacy of a timber mountain bike trail currently under construction.
The 'typical' detail is a 100x100mm post either side with a 200x38mm horizontal beam nailed between the two.
Vertical loading we can probably demonstrate by calculation that it works, however...
