Hi All,
I am currently working on a wooden fence post retaining wall solution designed by an Architect attached. I have been asked to calculate the attached, the problem is that I have calculated sheet piling using Gross Pressure Method in the past, but I am not sure if I can calculate the...
I am currently working on a large workshop with two roller door openings either end of the building; this workshop is located in England East Anglia. Does anyone have guidance on appropriate wind allowances for large workshops and buildings, I think a figure of 1.5KN/m^2 can be used?
Hi fellow Engineers,
Please see attached strip foundation with Plinth design. My problem is that I have never done a plinth wall design before only cavity walls etc. Can I place my cavity wall central to strip foundation as per normal ignoring Plinth? or do I need to add eccentricity to the...
Hi All,
The problem I have is that the foundation calculations prove that a 600 x 225mm strip foundation will be sufficient to take loads of the build in concern, but in the NHBC the minimum projection is 150mm, but The plinth wall I have is 360mm in total leaving me with 120mm projection will...
Hi all,
I have been been working to TR34 4 Edtion please find attached calculations. I have found that I have a higher positive load rather than a negative load in my moment's calculations and on other examples that I have been following they always have a higher positive moment for ground...
On a job I am working there is a number of garages that need to be built. The site has a clay soil with a medium-high volume change potential between 100-150mm and the ground bearing strength of the soil is 80-100KN/m^2. I was going to design a ground bearing slab 150mm thick with 150mm sub...
Hi All,
would it be sufficient to use below calculations for a slab supported on grade? I am working to book (Reinforced Concrete Design to Eurocodes Design Theory and Examples Fourth Edition)
simply supported two-way slab: Corners free to lift
* Design of moment reinforcement
* Shear...
Hi All,
I have a reinforced concrete slab with 50mm cover A393 mesh 10mm bars and the dimension are 6.19 x 3.031 and 150mm thick. This slab is going to have 150mm of grade under slab. Does anyone know the best design approach to take? I have been using EC2 codes, but I can only find simply...
Hi All,
I have been looking at the different live loads on a domestic house.
Is it appropriate to use 1.5UDL as stated in BS 6399: 1996 or should I use the slightly higher load of 2 KN/m^2 as indicated in building regulations Approved Document A Table 4 ?
Hi All,
in the regulations permanent partitions shown on the floor plans should be considered as dead load and flexible partitions which may be movable should be allowed for in the imposed loads, with a minimum of 1KN/m^2. I have been looking over some foundation calculations for domestic...
Hello I have a question regarding strip foundations
according to the NHBC a strip foundation minimum thickness should be equal to the projection 150mm and the depth of the foundation should be equal to the projection. This is to allow for the stress that works at 45 degree angles, but I have...
Hi All,
I have a two story house seperated by a party wall and I am working out the foundation sizes for the properties before they are built. I have a ground bearing strength of 100KN/m^2, so I have calculated the party wall to be taking a load of 60kN/m^2 on either side of the party wall. Does...
