Thanks, everyone for the comments. I think that it is probably best to use a concrete or brick structure below ground for the retaining part of the structure with a wooden fence attached above ground to the retaining wall as suggested in the comments. Good point retired13 the substation is...
That is another good idea, does anyone know how to calculate the tip elevation for a timber post using flowfill concrete to fix posts into the ground similar to attached drawing?
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 aware of the four stages of calculating wind actions on buildings following BS EN 1991-1-4 and its National Annex;
Calculation of the peak velocity pressure
Calculation of the structural factor
Determination of external and internal pressure coefficients
Calculation of wind forces
My...
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 All, sorry about my below average sketches, I have found two designs attached of the sort of Plinth wall I am talking about.https://files.engineering.com/getfile.aspx?folder=4283a088-eef1-42df-9880-04eefa3277a9&file=plinth_designs.pdf
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...
I have been in contact with a manufacturer of clay boards, and they are saying that clay boards can deform to make cavities of up to 160mm for situations such as my site with heave issues of 100-150mm. Has anyone used these before for similar circumstances?
Hi, Thanks for the comments. I have a geology team onsite at present, and they are doing the ground survey for the site, I will not have any real information till the end of the month. But they told me that the previous results to a place opposite my location have a firm to stiff clay and...
The garages are either a single garage or some are double garages only, but yes after talking to others in the industry, they are suggesting to stay with my original 150mm slab on 150mm grade, because it is a garage after all.
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 I have attached what i have calculated for the slab.
The slab is 6.19 x 3.031 x 0.150 meters and yes i no what i have calculated is not for a slab on grade, I was just trying to ascertain if the simply supported two way slab calculations attached could be used as an over estimate or...
With this method you Assume a 1 meter wide strip of the width and length of the slab, as shown on attachment. https://files.engineering.com/getfile.aspx?folder=d7c23eed-adbb-49a1-ac50-d5453779c71e&file=DCE158C4-BD1D-4503-8E6C-230D0E31F7F5.jpeg
