Hi there I've just moved from the London to Nairobi and am adjusting to the local construction practices... Currently designing steel trusses using small square hollow sections (30 - 75mm) with wall thicknesses from 3-5mm. Coming from the UK these sizes seem very small and while the analysis...

Hi, I'm trying to calculate active earth pressure on a retaining wall. One thing is bugging me; it makes sense to me that a more cohesive soil will 'hold itself together' better than a less cohesive soil (i.e. a clay vs a sandy clay) and will therefore apply a lower lateral load to a retaining...

Hi all, I am trying to justify an existing 2 storey RC building in the UK, to take some additional loading. The building was constructed in the 1950s. There is no evidence of any RC shear walls and as such we had assumed the structure to be acting as a sway frame for stability. The problem I...

Thanks for the responses guys. It's actually for a final year university project I'm doing and the lecturers are pretty reluctant to give much away. I've managed to source most of the relevant values from literature which I understand they deem acceptable. I'm stuck trying to find a bulk unit...

Hi there, I'm trying to design pile foundations. This will involve piling to a depth of around 25m through three different strata with the fourth being end-bearing. I am trying to determine reliable values for undrained shear strength and the adhesion factor in order to estimate my pile...
